Do you believe Pres.Bush when he says that if the intel had shown no WMD's the U.S. might not have invaded?

Two years before he took office? You need to show evidence of that one. Perhaps you are confusing this with plans that were constructed during the Clinton Presidency. If that were the case, remember, it was no secret that Sadam was a bad guy and deposing him could have always been a scenario, but so were other directions. It's called planning for different possibilities.
