Re: Could you
The notion that the Treaty of Versailles was unfair to Germany was a lie invented by the National Socialists in Germany to create a sense of resentment which the Nazis exploited.
"Fair" requires a value judgement. As such, it cannot be called "a lie" unless we have explicit agreement on what constitutes "fairness". Your uncompromising use of the objective term "lie" to describe an inherently subjective claim "fair" is either silly or disingenuous.
The most contentious clauses were about reparations, which were orders of magnitude larger than anything that had ever been imposed before, and were impossible for the crippled German economy to meet. (Not unlike the terms the Germans themselves recently imposed on the Greeks.) The French eventually forgave the debt of Austria, Hungary, Turkey and Bulgaria, but they held out for full repayment from the Germans. Was that "fair", in your understanding of the word?
Then there was the loss of Germany's colonies - not given independence, but ceded to the French and other allies. This was a substantial hit to the German economy at a time when it was already hobbled by the drain of the war effort and the loss of manpower, and it was being asked to pay billions of dollars in reparations. Was it fair to load all those strains on the economy at the same time?
At the end of the day, "fair" is what people agree it is. If one side feels so aggrieved that it's willing to fight - then the arrangement isn't "fair" enough, no matter how much the other side may like it.
