FDR led us into World War II. Germany never attacked us. From 1941-1945, 450,000 lives were lost, an average of 112,500 per year.
Truman finished that war and started one in Korea. North Korea never attacked us. From 1950-1953, 55,000 lives were lost, an average of 18,333 per year.
John F. Kennedy started the Vietnam conflict in 1962. Vietnam never attacked us. Johnson turned Vietnam into a quagmire. From 1965-1975, 58,000 lives were lost, an average of 5,800 per year. Nixon usually gets credit for Vietnam. He is the one who got us out.
Clinton went to war in Bosnia without UN or French consent. Bosnia never attacked us. He was offered Osama bin Laden's head on a platter three times by Sudan and did nothing. Osama did attack us.
In the two years since Osama's terrorists attacked us, President Bush has liberated two countries, crushed the Taliban, crippled al-Qaeda, put nuclear inspectors in Lybia, Iran and North Korea without firing a shot, and captured a terrorist who slaughtered 300,000 of his own people. We lost 600 soldiers, an average of 300 a year. Bush did all this abroad while not allowing another terrorist attack at home.
