Of course, Petraeus is trying to circumvent his commander-in-chief, which I believe they call insubordination:

The opening argument by the Petraeus-Odierno faction against Obama's withdrawal policy was revealed the evening of the Jan. 21 meeting when retired Army Gen. Jack Keane, one of the authors of the Bush troop surge policy and a close political ally and mentor of Gen. Petraeus, appeared on the Lehrer News Hour to comment on Obama's pledge on Iraq combat troop withdrawal.

Keane, who had certainly been briefed by Petraeus on the outcome of the Oval Office meeting, argued that implementing such a withdrawal of combat troops would "increase the risk rather dramatically over the 16 months". He asserted that it would jeopardise the "stable political situation in Iraq" and called that risk "not acceptable".

The assertion that Obama's withdrawal policy threatens the gains allegedly won by the Bush surge and Petraeus's strategy in Iraq will apparently be the theme of the campaign that military opponents are now planning.
