Surge or Not?

The Washington Post reports that some in the White House want to "surge" the troops; the military apparently is reluctant. If I understand, "surging" essentially means robbing Peter to pay Paul. You keep some troops on longer, you accelerate the deployment of other troops, and maybe you change some rules so you can use the Reserve/National Guard more often. Bottom line is you use assets today that you won't have tomorrow. So that gives some political logic to the WH position. Do the "surge". If it works, great. If not, even the right wing will say we've done all we could. That's cold logic for those who might be killed in the surge, but cold logic is the logic of statecraft.
