The Wall Street Journal ran an article last week (subscription req'd) that Bush was using an investigation into a 1994 terrorist attack on a Jewish Community Center in Argentina as a way to continue to strain and maintain pressure on Iran.
The only problem? There's no real evidence that Iran was involved in the bombing:
(I)t is impossible to avoid the conclusion that the case against Iran over the AMIA bombing has been driven from the beginning by US enmity toward Iran, not by a desire to find the real perpetrators.
Evidence? We don't need no stinkin' evidence. Nobody could anticipate the president initiating a pre-emptive war against a sovereign nation on trumped up evidence, could they? Oh...wait...
