Right, when Hitler invaded Poland the West should have looked for 'peaceful solutions' otherwise you're a 'warmonger'. Okay
I didn't define the word. Look it up.
The question was not what to do when Hitler invaded Poland, because the “West” did the right thing - nothing.
The correct question was what to do when, 17 days later, the Soviet Union invaded Poland. And what the “West” did then was to help the USSR.
