Not necessarily. Shooting at our planes in the no fly zone, for instance, was an act of war that went largely unpunished through the Clinton administration.
When all other excuses fail (or are proven false), always fall back to a philosophical reason that can't be argued definitively one way or another.
Seems to me that we could argue pretty effectively that we (1) aren't in favor of colonialism, particularly when we are the colonizers, and (2) it's not our business to decide what sort of government other countries choose to have.
But I have been wrong before.
Other countries have shot as US warplanes in the past without all out invasion being the end result. I refer you back to the SOTU speech in 2003. Most, if not all of it, was not true. At no point in that speech was the issue of 'no-fly zone' broached. There was one main reason forwarded. No fly zones had nothing to do with it.

I really don't see how you could argue either of those points effectively considering that actions by the US government in relation to the new government in Iraq have been the direct opposite
