In 1947, the Cold War came to Hollywood. Over nine tumultuous days in October, the House Un-American Activities Committee held a notorious round of hearings into alleged Communist subversion in the movie industry. The blowback was profound: the major studios pledged to never again employ a known Communist or unrepentant fellow traveler.

Hundreds of artists were shown the dooror had it shut in their faces.

Iran is a land of contradictions. It is an Islamic republic, but one in which only 1.4 percent of the population attend Friday prayers.

Throughout the war on the Eastern Front, there were two consistent trends. The Red Army battled to learn how to fight and win, while involved in a struggle for its very survival. But by 1944 it had a leadership that was able to wield it with lethal effect and with far more effective equipment than before. By contrast, the Wehrmacht had commenced a slow process of decline after the invasion of the Soviet Union. Hitler became increasingly unwilling to delegate decision-making to commanders in the field, which had been crucial to earlier success.
