I guess Hitler had nothing to do with it. Tell me, do you never hold people responsible for their actions? Or do you only not hold people responsible when it suits?
It was Woody Wilson's intervention that made the allied victory possible and THAT led to Hitler. Even Churchill noted this, not long after WWII. You could ALSO make the case that the instability of WWI in Russia led to the 1917 Revolution and the takeover by the Reds after it.
You'd be well advised to actually STUDY history before you regurgitate your public school pap.
