"We have to do something. Don't pretend we can look away."
Looks like a declarative sentence to me.
I don't understand your point. And I don't believe Bush is engaging in semantics, he is acknowledged as very plain spoken, and I think it's one of his strengths. You don't see him tip toeing around issues, in an attempt to avoid a question. If he isn't ready to answer a question he doesn't. In fact his whole administration is plain spoken, especially Rumsfeld. It makes them look very competent, and reassuring. But this speech was a blunder, he sacrificed the moral high ground, for little or no political gain. The authoritarian establishment in the middle-east will never support the replacement of one of their own(Iraq), with a democracy. These people only come to power by stepping over the corpse of their predecessor. They intend to die in office, not be voted out.
