And what do you think people should think motivates the "resistance fighters"?

The desire to set up a tyrannical regime with themselves in absolute power and the people of Iraq under their boots. This applies both to ex-Baathists and Islamic radicals. The end result--oppression and death--is almost exactly the same, regardless of the label.

Blowing up a U.N. facility is an act which has no real effect at all on the U.S. coalition. The only thing it accomplishes is to hurt the Iraqi people. The motivation is not anti U.S. It's anti free Iraq.

For the record, I think they are motivated by a strong desire to have the US coalition out of Iraq.

If Iraq was ruled by a democratic government and the U.S. had long ago left, these pro-tyranny forces would be doing exactly the same things: bombing pipelines, blowing up buildings, and killing Iraqis, until their ideal form of totalitarian government was instituted--ruled by some Saddam wanna-be or some Taliban-type ayatollah. The U.S. occupation is a convenient excuse that helps recruit cannon fodder to their cause, much the same way as Israel is the excuse for the current rulers of the Palestinians to push their own totalitarian agenda.

And yes, the image of these terrorists (and the U.N. bombing WAS a terrorist act) as noble "resistance fighters" is exactly the one promoted by the Left, and plays right into the hands of these thugs. The Palestinian rulers have been playing the Left like a fiddle for decades along these same lines.
