There has been some discernible shift in conditions lately...virtual admission of defeat on finding WMD in Iraq, appearances of stagnation in the Sunni triangle. The elections will likely be a PR coup for Bush. I suppose that's why the Dems may be less fervent for the moment.
If Bush goes over the Iranian or Syrian borders, I bet that's when they will go ballistic, perhaps for impeachment. It does seem that something needs to happen to get us out a rut in the Sunni triangle.
The Sunnis may wake up to realize that the train is leaving the station, and they'd better get on board quick if they don't want to get rolled by the rest of the Iraqis. Their complaint is lack of representation as the minority. Well, that's what elections and a constitution are for....they refuse to participate at their own peril.
As Victor Davis Hanson says in this article, "The suicide bombs and explosions that go off daily in Iraq are not proof that Americans are losing the Sunni Triangle, but rather that thousands of secular and religious fascists are desperate not to lose their entire Middle East."
I believe the Sunni triangle terrorism is the 21st century equivalent of the Marxist terrorism before the El Salvadoran elections, and I believe it will fail as utterly.
