Quit with the nev chamberlain jive. Hitler didn’t have the means to destroy Britain, France etc in a few strikes. If he did ww2 woukdn’t have happened.The more apt comparison if you want to make them is Nato against Sebia and Russia against Ukraine. The former excised a part of a sovereign country to give mad mo followers their own space. make bent dick look good. The latter are going to do the same for Russians in East Ukraine.
I was never a fan of the NATO Serbia action. Didn’t think then or now it was smart or warranted.
So your argument is probably the closest I have heard to an analogy yet to justify Putin’s actions. But two wrongs do not make a right. They were/are both wrong and evil.
