Unilateralism
France had reached an "honorable peace." Poland, Czechoslovakia, and Austria's opinions had been given due consideration. The United States, Russia, Japan, and Sweden, among others, remained neutral. Italy and Germany voiced strong opposition. Yet despite the fact that international opinion seemed to be against them, from the fall of France in June 1940 until the invasion of the Soviet Union in June 1941, the United Kingdom stood alone against Nazi Germany. I find this blatant unilateralism both arrogant and hawkish. How dare the British go into a war without the support of their closest ally, the United States. Winston Churchill was the greatest threat to world peace at the time. Germany, German-occupied France, and "independent" Vichy were all against Britain's "Bring 'em on" stance, yet the British continued to flaunt international opinion. I am shocked that the League of Nations was too cowardly to condemn Britain for her rogue conduct.

(The moral of the story? Just because you are alone doesn't mean you are wrong.)
