You repeat this over and over again, BBoy. Unfortunately, Treaty of Versailles can explain the outbreak of WWII and what the Nazis had done during it, but it certainly cannot justify it.
Who want's to justify a war? Any war?
Explaining is enough...
He does at times give a different impression, though.
WWI was a fight for power between the old bullies and the new one.
After a combined effort the new one was shown his place and due a treaty it was tried to keep him down.
Holding down an industrious, highly industrialized and technological savvy (and miffed) people of 80 millions in the heart of Europe proved to be impossible...
WWII followed, worse than the first one.
Another joint effort was needed again to stop the madness but instead another vindictive "hold the hun down
" kind of treaty it was seen by another new "kid" on the block (the only one with real power now)
without all the european baggage and centuries old powergames and grievances that the balance in Europe was changed nevertheless.
The old bullies lost their empires, the new bully was being pacified and all more or less pressed into a kind of structure which made any further war kind of senseless....
You were saying?
