"Worst" President?

The following appeared in the Durham, NC local paper as a letter to the editor:

Liberals claim President Bush shouldn't have started this war. They complain about his prosecution of it. One liberal recently claimed Bush was the worst president in U.S. history.

Let's clear up one point: We didn't start the war on terror. Try to remember, it was started by terrorists on 9/11.

Let's look at the "worst" president and mismanagement claims.

FDR led us into World War II. Germany never attacked us: Japan did. 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.
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 has attacked us on multiple occasions.

In the two years since terrorists attacked us, President Bush has liberate two countries, crushed the Taliban, crippled al-Qaida, 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 30 a year. Bush did all this abroad while not allowing another terrorist attack at home.

Worst president in history? Come on!
