re: Obviuosly Churchill knew he was making horrible decisions.

I love that classic scene in Dunkirk (I know fabricated for cinematic effect). The US congress forbids assistance for the war, parliament is licking their chops because he has not surrendered and Dunkirk is a shot to the heart. The weight of the whole world on his shoulders....and dont think it cant get worse, his car breaks down on the way to Parliament. He hops on a city bus and the people are aghast...its the man in real life. Totally silent they look at him with his head bowed.

And the one kid says to him "Sir, I say we fight" and the whole bus erupts. He goes to parliament and says "...we will fight them in the fields......we shall never give up.
