War

Seventy-five years ago, Americans nearly unanimously supported the U.S. government's decision to declare war on Japan for its Dec. 7, 1941, attack on Pearl Harbor.

In the weeks after the U.S. dropped nuclear bombs on Japan, effectively ending World War II, most Americans thought the development of the atomic bomb was a good thing. But when Gallup last measured this, in 1998, attitudes were nearly reversed.
