Otherwise there might still be terrorism.
I think Bush was right to let Bin Laden go and attack Saddam. This latest terrorist shows Saddam Hussein is still orchestrating Al Qaeda attacks from the grave. Imagine what he would have done if we left him alive.
I'm not sure what we do about Saddam now. Hang the guy, kill his offspring, take over his country...nothing seems to stop him. We should check with Dick Cheney and the GOP. Maybe the chemical weapon factories were converted to time machines just before the invasion. We need more GOP national security genius right now.
My two cents.
