Bush: Iraq gov't 'still has some maturation to do'

President George W. Bush said the unruly execution of Saddam Hussein "looked like it was kind of a revenge killing," making it harder to persuade a skeptical US public that Iraq's government will keep promises central to Bush's plan for a troop increase. In his toughest assessment yet, Bush on Tuesday criticized the circumstances of Saddam's hanging last month, as well as Monday's execution of two top aides, including Saddam's half brother. "I was disappointed and felt like they fumbled the - particularly the Saddam Hussein execution," the president said in an interview with PBS' Jim Lehrer.
