Apparently Bush thinks the word surge

Means long-term escalation:

WASHINGTON (Reuters) - The U.S. Army said on Friday it was sending some 2,600 soldiers to Iraq earlier than planned, raising the number of extra U.S. troops being deployed in a new effort to stabilise the country to nearly 30,000.

News of the latest deployment came as Democrats who now control Congress pushed legislation to end a war that is increasingly unpopular in the United States.

The combat aviation brigade from the U.S. Army's Third Infantry Division would deploy in early May, some 45 days sooner than previously envisaged, the Army said.

The brigade is the third element to be announced in a package of support units being deployed to assist 21,500 extra combat troops ordered to Iraq under a plan unveiled by President George W. Bush in January.

"The aviation brigade, which is really principally rotary helicopter support for the troops, is the final piece," U.S. Defence Secretary Robert Gates told reporters.

There are more than 140,000 U.S. troops already fighting in Iraq, where sectarian violence has thwarted American efforts to bring the four-year-old war to a close.

Or this is Bush's do-over since things are falling apart. We have to fight for his legacy, you know.
