The Surge.

While reading Sullivan defend Joe Klein, I came across this nugget:

Last December, as Rumsfeld was leaving, President Bush met with the Joint Chiefs of Staff in 'The Tank,' the secure room in the Pentagon where the Joint Chiefs discuss classified matters of national security. Bush asked the Chiefs about the wisdom of a troop 'surge' in Iraq. They were unanimously opposed.

The JCs must not have heard that "opposition to the surge is wrong."
