“Are we the terrorists or are they the terrorists? Two wrongs don’t make a right,” Bennett told Stern after being asked about how America should handle terrorism.

“They [the terrorists] flew the plane in, but we caused it,” Bennett continued. “Because we were bombing them and they told us to stop.”

The 85-year-old said serving in World War II, and seeing a dead German soldier for the first time, made him “anti-war” and a “pacifist.”

“It’s the lowest form of human behavior,” he said.

He extended this pacifism to the war in Iraq, which he said “was a tremendous, tremendous mistake internationally.”

Bennett also claimed that at the 2005 Kennedy Center Honors, then-President George W. Bush told him of the Iraq conflict, “I think I made a mistake.”
