Jimmy Carter: US has only enjoyed 16 years of peace in its 242-year history

“Since 1979, do you know how many times China has been at war with anybody?” Carter asked. “None. And we have stayed at war.” The U.S., he noted, has only enjoyed 16 years of peace in its 242-year history, making the country “the most warlike nation in the history of the world,” Carter said. This is, he said, because of America’s tendency to force other nations to “adopt our American principles.”
