Considering that the war was brought about by treaties and international financial pressure, it was pretty much inevitable.

The last thing that international finance wanted was yet another destructive world war. Secondly, there was no treaty with Poland, just a guarantee.

So no, it was not inevitable, but I understand why it is in your interest to pretend that it was.

By removing the stigmata from Nazism it therefore strengthens the position of Nationalism and creates another platform to counterattack the Bolsheviks.

You're never removing the stigma from Nazism, and by trying to do so, you're associating what you view as your own ideology with Nazism - thus discrediting yourself.
