Victor Davis Hanson answers three questions:
1. Why did the Japanese so foolishly attack Pearl Harbor?
2. Why did the Germans attack the Soviet Union so recklessly at a time when they had all but won the war?
3. Why did the United States stop after spring 1951 at the 38th Parallel, thereby ensuring a subsequent sixty-year Cold War and resulting in chronic worries about a North Korea armed with nuclear weapons and poised to invade its neighbor to the south?
