Moral Cowardice

TPM:

On the one hand you have Kerry, who already had doubts about whether we should be fighting in Vietnam before he went, and put his life on the line anyway. On the other hand, you have George W. Bush who supported the war, which means he believed the goal was worth the cost in American lives. Only, not his life. He believed others should go; just not him. It's the story of his life.

That is almost the definition of moral cowardice.
