Strengths and Weaknesses of the Treaty of Versailles

Strengths and Weaknesses of the Treaty of Versailles On the 28th June 1919, Germany resentfully signed the most famous treaty ever, Versailles. Although years of readjusting the treaty followed, this essay will focus mainly on the strengths and weaknesses of the 440 articles in 1919. The Treaty followed a massive war, with huge human sacrifice. It was supposed to be the Treaty to end all wars and give security to the countries involved. The overwhelming task that laid ahead for Woodrow Wilson (America), Lloyd George (Great Britain), Clemenceau (France) and Orlando (Italy) was on a bigger scale than any previous delegates had had to deal with. One of the biggest interpreted weaknesses was the economics and reparations. Firstly, it highlighted the weaknesses of the delegates forming the Treaty, as they had to listen to public demand which had been exaggerated due to the scale and length of the war. An example was Lloyd George who was pressured from conservatives for harsh reparations, Geddes, a conservative politician hailed the words we shall squeeze the German lemon until the pips squeak.  [1]  Packer declared Lloyd George did not believe in harsh reparations  [2]  , but George added extras to the original reparations such as war pensions to please the conservatives because the original amount based on war damage gave Britain a very little. Kitchen showed and I agree that there was little Lloyd George could do about the situation as no politician would have survived if he had suggested that Germany should be forgiven.  [3]  However, Lentin disagreed, thinking that public opinion created pressure but had no imp act on the Treaty. He later contradicted himself by proclaiming that the one of the causes of the delay in announcing reparations because the delegates believed that the public would never be satisfied with the guaranteed amount.  [4]  Therefore, public opinion had to be acknowledged and satisfied to a certain extent. This meant the Treaty did not always accomplish what was needed such as lower reparations. The biggest weakness with the reparations was the total amount ( £600 million) Germany had to pay. Keynes, who scathingly criticised the Treaty of Versailles, heavily condemned the reparations as Britain depended on the revival of trade, especially with Germany,  [5]  but Germany needed to increase their exports and decrease their imports. This would decrease trade with Britain and lose Britain money. Feldman, although I disagree, supported Keynes believing that the economic and financial settlements were horrendous failures.  [6]  This was an extreme view and seemed to ignore the circumstances the delegates were dealing with. There were poor decisions but Feldman over-exaggerated. Nicolson argued that it was not excessively harsh economically to Germany.  [7]  However, although it was not excessively harsh, I believe it was too harsh for Germany to even begin to comprehend, especially when territory and economics are combined. Germany lost 13.5% of their territory incl uding 8% of German coal production. Germany lost 10% of her population as well as 1.7 million people in the war. Population creates manpower for industry. This might not seem a lot however, when you add  £600 million in reparations, the loss can seem great and perhaps the Treaty harsh. This shows another weakness of the Versailles Treaty, as no suitable amount for Germany to pay was reached discrediting the treaty. However it could be deemed an unavoidable weakness as the reparations were decreased in the 1920s but the Germans still felt it was unfair. Another weakness of the Treaty of Versailles was the disarmament hypocrisy. The League of Nations articles asserted that any discrepancies would be sorted through the League and not by war. Therefore there was no need for any country to have large armies; however Germany was forced to disarm to a 200,000 volunteer army, showing how the points were used selectively. During the revisionist period Germany complained about the unjust nature of disarmament. Therefore disarmament can be viewed as a weakness as it highlights the unjust part of the Treaty but it shows that Germany was always going to come back with revenge. Germany was unified in its pride in its military. Carr argued that Germanys rise in 1920s was inevitable as it was unreasonable to impose a position of permanent inferiority on a great power.  [8]  This was true, but unavoidable; France wanted to know that Germany could not attack them. However, if the hypocrisy previously mentioned did not exist, and everyone had dis armed, then the situation could have been different. Isolating Germany in disarmament and the League of Nations was a bad idea, as they used it as an excuse to break the Treaty later, which was one of the causes of the Second World War. The Treaty had the aim of prolonged peace, and the isolation through disarmament was one of the reasons it did not fulfil its aim. The failure of the League of Nations was a huge weakness; it failed because America, Russia and Germany were omitted. The League could not make decisions about the world without three of the most influential countries. The League was bypassed when Italy seized Corfu, causing embarrassment for the League as it showed a lack of power. The League might not have been certain to succeed, but if the League had put its countries beliefs behind, and the worldwide affairs first, it would not be deemed such a weakness. The League of Nations had strengths too, it was the first time the idea have been put into practise trying some ideologically and practically new to keep the peace worldwide. The League introduced medical measures that had not been in states before 1914. This was a very credible strength from the Treaty of Versailles. It really was evidence of the Versailles Treaty trying to keep prolonged peace. The compromises in the Treaty created strengths and weaknesses. These compromises had left historians to debate as to whether the Treaty would have been stronger if it had been harsher or softer. Marks perfectly described the Treaty as too soft to restrain Germanyà ¢Ã¢â€š ¬Ã‚ ¦ yet too severe to be acceptable toGermans.  [9]  It was viewed too harsh in terms of reparations, disarmament and territory. The consequence of this was Germany convincing others it was too harsh bringing the revisionism viewpoint of the 1920s which had been adopted by Britain. Revisionism allowed the Germans to undo some of the Treatys main clauses such as self-determination, reparations and disarmament. Revisionism has been linked to the rise of Nazism and also the Second World War. The Versailles Treaty aimed to keep prolonged peace, the weakness of the compromise shows a failure of the Treaty. A soft treaty would have been impossible, the after war feeling was to enforce a vindictive peace to help res tore some of the hurt caused during the war that Germany was blamed for starting. However , it seemed that no matter how soft the Treaty would have been Germany would have wanted to change it. I agree with Kitchen that ultimately no amount of revision would have satisfied the Germans.  [10]   The strength of the Versailles Treaty compromises was that most of the clauses were very just, especially considering the circumstances. An example of this would be the Rhineland, France wanted to occupy it, however the other delegates knew that it would only cause outrage in Germany, and would strike revenge, therefore they created a compromise where the Rhineland would remain unoccupied and demilitarized. Another way to view the compromises as strength is looking at Germanys Treaty of Brest-Litovsk, an obviously overly harsh Treaty imposed on Russia after they withdrew from the war. This strength does not disregard mistakes in the compromises and in the Treaty; however it highlights that within the circumstances it was a commendable agreement. However, the strengths and weaknesses could be argued to be unavoidable. The Treaty regardless of its content was never going to last. Mattrl pointed out the undeniable point that before the ink had dried on the Treaty of Versailles, the move ment to destroy ità ¢Ã¢â€š ¬Ã‚ ¦had begun.  [11]  Therefore the weaknesses mentioned would not have been weaknesses had German accepted losing the war and the terms. The Treaty would not have been so heavily criticised and littered with failures if it had been enforced. The Treaty could have been successful but once the Treaty had been signed; the alliance had crumbled, worsened by different ideas on how to enforce the Treaty. France wanted to make sure the clauses were imposed on Germany as harsh as possible; however Britain began to revise the Treaty. Germany complained about the Treaty, believing it was unjust, when in reality it was mainly fair. For example, if disarmament had been enforced, Germany would not have been able to annex Czechoslovakia, which was a cause of the Second World War. Germany was also left to decide about whether they could afford the reparations, and obviously, as they did not want to have this article imposed on them, they often escaped doing it, to a standard that could easily create weaknesses in the Versailles Treaty. Marks correctly explained that the delegates erroneously believed that Germany would abide by thei r decisions,  [12]  this highlighted one of the many reasons why enforcement of the Treaty failed. Another reason for the lack of enforcement was that the allies were not loyal to each other; they just won the same war that they fought for different reasons. Therefore, the Treaty could be argued to have exposed weaknesses due to the lack of enforcement as opposed to the original articles. It can be argued that there are less strengths than weaknesses in the Treaty of Versailles but it is often forgotten that the biggest strength is far more significant than most of the weaknesses. The momentous task that lied ahead of the delegates was incomprehensible; 10 million people lost their lives alongside the new style of warfare. The war came to an abrupt end and there were complex issues alongside contradicting viewpoints. The short amount of time they had, and the amount they had to handle creates the strength as they were able to form a Treaty which although has been criticised with many weaknesses, also has commendable articles and decisions. It must never be forgotten that the Treaty was produced attempting long-term peace whilst punishing the losers of the war, as most Treaties do. If the Treaty had been accepted by the Germans, it could have been an established peace settlement. In conclusion, there are many strengths and weaknesses of the Treaty of Versailles, from the ideological revolution in the League of Nations, to the lack of considered economics in the reparations and loss of territories. However, the Treaty should be commended as one of its own time, that regardless of its contents would have been changed and adjusted as no Treaty had ever involved so many world and European powers. Marks convincingly summed up the Treaty by rightly claiming that the Treaty was a product of its time representing the feelings of the time; therefore its duration was limited seeing as the reality of the feelings of 1919 was limited.  [13]

Applications of cryptography

Looking for the â€Å"best† websites in cryptology is a daunting, if not an impossible task. This is because, as I started searching the Web for interesting sites on cryptology, I found that there are just so many. The task is made even more difficult by the fact that cryptology is such a broad subject which encompasses several sub-subjects. Nevertheless, I have to choose three sites. Basically, I just set two criteria for choosing a site: it has to be interesting and it has to be easily understandable even when the content is technical.Being a history enthusiast, my search for fascinating contents led me to a website that features cryptology in the 16th and 17th centuries. It can be accessed via the link http://home. att. net/~tleary/cryptolo. htm and is written by Thomas (Penn) Leary. One of the reasons I was drawn to this site is the existence of an author for the site. With internet access and blogging accessible to almost everyone, I tend to get wary of websites whose aut hors are unknown for I feel that this lessens the reliability of the site and its contents, unless the site belongs to a company or organization whose reliability cannot be questioned.The content starts with a philosophical statement by Blaise de Vigenere, something which I found quite endearing. Being primarily a non-technical site, it avoids the use of cryptographic jargon and instead uses words easily understandable by almost any reader. Examples of the early kinds of cryptology such as the Elizabethan cryptology (uses numbers to encipher letters) were discussed in the site. Several paragraphs in the site are attributed to Johannes Trithemius, a German monk who is also considered the first theoretician in cryptography.Most of his schemes also include steganography, a close cousin to cryptography, which involves concealing the existence of the message itself. Aside from that, Trithemius contributed much to the existence of polyalphabeticity. His tableau, which he called his  "tabula recta†, uses the normal alphabet in various positions as the cipher alphabets. Giovanni Battista della Porta, another famous early cryptographer received a highlight in the site. Likewise, the use of acrostic, a cipher which involves using the first letters of a poem in order to form a word, was also given emphasis.Poets in the Italian Renaissance and during the Elizabethan period were reported to be quite fond in using acrostic. Although quite non-technical, this website appealed to me because I can look back and trace the early days of cryptology when there were no computers and other modern crypto graphing equipment. It is fascinating to note that the state-of-the-art cryptography used nowadays evolved from relatively simple ciphers such as Trithemius’ tableau and acrostic. In terms of information presentation, the website did quite well and the information was arranged in a clear and systematic manner.Furthermore, the author cited several works which I find commendable as most of the websites today obtain information from other sites, books and journals without acknowledging these sources. As for the technical side, I found David Wagner’s (1999) discussion of the Boomerang Attack quite interesting. His paper can be accessed by this link: lasecwww. epfl. ch/intranet/proceedings-iacr-98-03/papers/1636/16360156. pdf, although I believe it originally came from www. cs. berkeley. edu/~daw/papers/boomerang-fse99. ps. As you might have noticed I’m quite a stickler for the reliability of website contents.Apart from the topic being quite interesting, I chose this website because it came from an academic institution, which I believe screens articles and papers before posting it in their website. Even for non-technical readers, Wagner’s (1999) introduction to the concept of a boomerang attack is quite comprehensible. He started by describing differential cryptanalysis, a powerful cryptanalytic technique. Because of such power , differential analysis has been used to break many published ciphers. Block cipher designers therefore ensure that their design is secured from differential attacks.Algorithm designers usually compute an upper bound p on the probability of any differential characteristic on the cipher. The designer then invokes an often repeated â€Å"folk theorem† stating that any successful differential attack will require at least 1/p texts to break the cipher, thus making a conclusion that the cipher is safe from differential attacks. In order to prove this â€Å"folk theorem† false, Wagner (1999) exhibited an attack – in this case the boomerang attack – that allows an opponent to beat the 1/p bound in some cases.Let’s say the best characteristic for half of the rounds of the cipher has a probability of q, a successful boomerang attack will therefore need O (q-4) chosen texts. In some cases, q-4 > 1/p, in which case the boomerang attack will be able to beat th e folk theorem’s bound. Basically, a boomerang attack is still a differential-style attack but does not try to cover the whole cipher with a single pattern having a significantly large probability. Instead, the attacker tries to find two highly-probable patterns, though not necessarily related to each other, but when taken together can cover the whole cipher (Standaert, Piret, Quisquater, 2003).Wagner (1999) does not only discuss boomerang attack theoretically and only through probabilities, he showed how boomerang attack can be used to break COCONUT98, a cipher that rely on decorrelation techniques for its design. The breaking of COCONUT98 suggests that decorrelation design may fail to give enough security against advance differential attacks when caution is not taken. Therefore the use of decorrelation techniques is not a total guarantee of safety against differential-style attacks.Nevertheless, a decorrelation design still improves the cipher’s security such that in the absence of a decorrelation module, COCONUT98 will be more vulnerable to conventional differential-style attacks. Wagner (1999) also demonstrated the use of boomerang attacks on Khufu and FEAL, and included a description of â€Å"inside-out attack†, a dual to boomerang attack, with the boomerang attack working from the outside, while the â€Å"inside-out attack† works from the inside. In general, the site is very informative but I must admit, quite technical.One therefore does not approach it without having received a background on cryptology. Oliver Pell’s (nd) website, which he claims has won him a prize in a mathematics essay contest, is just as interesting. Accessed from http://www. ridex. co. uk/cryptology/#_Toc439908875, it presents a very useful overview of cryptology. Slightly technical, it comes in between the first two websites. Whereas the first is definitely non-technical while Wagner’s (1999) paper is definitely technical, Pell (nd) prese nts technical data in the simplest way possible.In fact, among the three sites, this one definitely stands out. The website content begins with the definition of commonly-used cryptographic terms, an indication that the paper is meant to be read by a wide range of audience including non-technical ones. The history of cryptography and cryptanalysis which followed the definition is quite fascinating and seems to me, well-researched. Ancient Egyptians, Hebrews and Assyrians already developed a crude form of cryptographic systems.Later on, the Greeks invented the first transposition cipher but it was the Arabs who were the first to have a clear grasp on the principles of cryptography and elucidated the beginning of cryptanalysis. In the more modern times, the uses of cryptography during the First and Second World War were also discussed. What follows is a detailed discussion on cryptography starting on how cryptographic systems are grouped: based on the mathematical operation that chang es the plain text into ciphertext using the encryption key, based on whether a block or stream cipher is produced, and based on the type of key used, whether single or two key.Substitution ciphers – ciphers wherein the units of the plaintext are replaced with symbols or group of symbols, transposition ciphers – rearranging of the letters of the plaintext without actually changing the letters themselves, block ciphers – symmetric-key encryption algorithms that changes a fixed length block of the plaintext into the same length of cipher text, and stream ciphers – also breaks plaintext into units but usually a single character are just some of the ciphers discussed in greater detail under the single key cryptography.A problem in cryptography – the key distribution problem – is also tackled. Such a problem usually occurs because both the sender and the receiver hold a copy of the key, but must also prevent others from getting access to the key. The solution to this problem, the two-key cryptography, is also discussed. Briefly, a two-key cryptography enables a user to possess two keys – one public and one private – with the public key used to encrypt the data to be sent, and the private key used to decrypt it.Some common applications of cryptography, such as protecting confidential company information and protecting a phone call just to name a few, are also presented. In general, the topic (Cryptography) is really well presented. At times when the topic gets a bit too technical (like algorithms), the author presents examples in order for the topic to be better understood. Such a well presented website content is quite uncommon and indeed deserves a prize. References Leary, T. (1996 July).

Capitalism The Highest Stage Of Capitalism - 1538 Words

Since Vladimir Lenin was a Marxist and socialist he was opposed to global capitalism, and his book of Imperialism: The Highest Stage of Capitalism points out some of his main arguments regarding the capitalism as a whole. He regarded World War 1 as an imperialist war, caused by pressures that arose from an immediate development of several European empires. The central nations of capitalism participated to expand their exploitative sphere, which led to the conflict of interests and eventually produced the Great War . Although in Imperialism: The Highest Stage of Capitalism, Lenin characterized capitalism as a source of gaining the great profit, a closer reading of his narrative suggest that capitalism leads to a class exploitation by maximization of power, and total control of the economic system. The key to understanding the effect of capitalism and the power control can be seen in Lenin’s concentration of production and monopolies, which he described in his book. He believed that monopoly was a switch from capitalism to a higher system, and based on Marx’s law of concentration the market supremacy in capitalism belongs to a few cartels, syndicate and trusts, and emerging capital of banks that handle the thousands of millions. In addition to this, cartels, syndicates and trusts divide among themselves the whole internal market of a particular country, and enact their control that gives them a various power over the society and whole system.

Exclusion Restrictions in Instrumental Variables

In many fields of study, including statistics and economics, researchers rely on valid exclusion restrictions when they are estimating outcomes using either instrumental variables (IV) or exogenous variables. Such calculations are often used to analyze the causal effect of a binary treatment. Variables and Exclusion Restrictions Loosely defined, an exclusion restriction is considered valid so long as the independent variables do not directly affect the dependent variables in an equation. For example, researchers rely on randomization of the sample population in order to ensure comparability across the treatment and control groups. At times, however, randomization is not possible. This may for any number of reasons, such as lack of access to suitable populations or budgetary restrictions. In such cases, the best practice or strategy is to rely on an instrumental variable. Simply put, the method of using instrumental variables is utilized to estimate causal relationships when a controlled experiment or study is simply not feasible. Thats where valid exclusion restrictions come into play.   When researchers employ instrumental variables, they rely on two primary assumptions. The first is that the excluded instruments are distributed independently of the error process. The other is that the excluded instruments are sufficiently correlated with the included endogenous regressors. As such, the specification of an IV model states that the excluded instruments affect the independent variable only indirectly.   As a result, exclusion restrictions are considered observed variables that impact treatment assignment, but not the outcome of interest conditional on treatment assignment. If, on the other hand, an excluded instrument is shown to exert both direct and indirect influences on the dependent variable, the exclusion restriction should be rejected. The Importance of Exclusion Restrictions In simultaneous equation systems or a system of equations, exclusion restrictions are critical. The simultaneous equation system is a finite set of equations in which certain assumptions are made. Despite its importance to the solution of the system of equations, the validity of an exclusion restriction cannot be tested as the condition involves an unobservable residual. Exclusion restrictions are often imposed intuitively by the researcher who must then convince of the plausibility of those assumptions, meaning that the audience must believe the researcher’s theoretical arguments that support the exclusion restriction. The concept of exclusion restrictions denotes that some of the exogenous variables are not in some of the equations. Often this idea is expressed by saying the coefficient next to that exogenous variable is zero. This explanation may make this restriction (​hypothesis) testable and may make a simultaneous equation system identified. Sources Schmidheiny, Kurt.
