re: Obviuosly Churchill knew he was making horrible decisions.

At one point during the blitz the codebreakers at Bletchley Park told him the german bombing raid that night would not be London but another city they had not bombed before. It would be lit up, no one in bomb shelters, total defenseless.

And Churchill said do not alert them, if we do the Germans will come to no other conclusion but that we have broken their code. That takes some brass balls there. And the kind of leader you need during a war.
