The escalation began before he even gave his speech. Stick a fork in democracy and call it done.

BAGHDAD, Iraq, Jan. 10, 2007 - President Bush’s speech may be scheduled for tonight, but the troop surge in Iraq is already under way.

ABC News has learned that the “surge” Bush is expected to announce in a prime time speech tonight has already begun. Ninety advance troops from the 82nd Airborne Division arrived in Baghdad Wednesday.

An additional battalion of roughly 800 troops from the same division are expected to arrive in Baghdad Thursday. Eighty percent of the sectarian violence occurs within a 30-mile radius of Baghdad, so that is where most of the additional troops will be concentrated.

It is the first small wave of troops in a new White House strategy that is expected to put more than 20,000 additional U.S. troops on the ground in Iraq and likely require new call-ups of the National Guard.

The president is expected to deliver his announcement about the troop increase, a plan that has already met with stiff criticism from many members of Congress, in a speech tonight from the White House.
