Back in 2005, or before he became a fixture in Fox News, Charles Krauthammer reminded us of another parent who said unkind things about a war President.
Check this out:
"'Harry, what the hell are you doing campaigning for that crippled son-of-a-bitch that killed my son Joe?' [Joseph P.] Kennedy said, referring to his oldest son, who had died in the war. Kennedy went on, saying Roosevelt had caused the war. Truman, by his later account, stood all he could, then told Kennedy to keep quiet or he would throw him out the window." ("Truman," by David McCullough, Page 328)Harry is soon to be VP Truman. The cripple is Pres. Roosevelt. Joe is 20-something Joe Kennedy, who was killed in Germany. The critic is Joseph P. Kennedy, father of a future President and two Senators.
Anyway, here is the book. It is a wonderful biography:
