Well, that explains it. The Iraqi defector whom U.S. intelligence used to prove that Iraq had a weapons of mass destruction program says he invented the whole thing in his desperation to topple Saddam Hussein. Rafid Ahmed Alwan al-Janabi, nicknamed “Curveball,” said he didn’t expect that his lies would form the justification for the invasion of Iraq and Colin Powell’s infamous U.N. speech on the eve of the war. But he doesn’t feel bad about it. “I wanted to get rid of him and now I had this chance," said Janabi, who is living in Germany after receiving asylum there.
