Otherwise known as "speaking the truth".
One of the worst crimes of WWII was the surrendering of Eastern Europe to Stalin; the war that started when Britain & France went to war to defend Poland (oddly enough, only declaring war against Germany, invading from the west, while ignoring the Soviet invasion from the east that actually resulted in the Katyn massacre) resulted in Poland (and many other countries) being given to Soviet masters instead of Nazi masters.
Churchill realized this at the time and was furious; the Western allies fought for (and got) nothing.
