Taking Credit for Gravity

From the New York Times editorial this morning:

The headline out of General Petraeus’s testimony was a prediction that the United States should be able to reduce its forces from 160,000 to 130,000 by next summer. That sounds like a big number, but it would only bring American troops to the level that were in Iraq when Mr. Bush announced his “surge” last January. And it’s the rough equivalent of dropping an object and taking credit for gravity. The military does not have the troops to sustain these high levels without further weakening the overstretched Army and denying soldiers their 15 months of home leave before going back to war.

Petraeus tells us we need 6 more months. How many times have we heard that?
