"Could"

McClatchy's Matt Stearns writes that "Taking military action against Iran could put President Bush on a collision course with Congress, leading Democrats and a Republican lawmaker cautioned Friday following Bush's threat of unspecified consequences for alleged Iranian meddling in Iraq." You'd like to think that starting a second war would rather than could set Bush on a collision course with congress.

That said, considering that congress was willing to cave to Bush on FISA and, eventually, on Iraq funding I don't think Bush seriously needs to worry that congress would stop him from starting a war with Iran or, for that matter, Venezuela. The Democratic majorities aren't large ones, and plenty of Democrats still seem to think the appropriate response to Bush yelling "Boo! National security! Here's my plan to make everything much worse!" is surrender.
