From today's Wash Post:
When President Bush goes before the American people tonight to outline his new strategy for Iraq, he will be doing something he has avoided since the invasion of Iraq in March 2003: Ordering his top military brass to take action they initially resisted and advised against.
Bush talks frequently of his disdain for micromanaging the war effort and for second-guessing his commanders.
"It's important to trust the judgment of the military when they're making military plans," Bush told The Washington Post in an interview last month. "I'm a strict adherer to the command structure."
... Pentagon insiders say members of the Joint Chiefs of Staff have long opposed the increase in troops and are only grudgingly going along with the plan because they have been promised that the military escalation will be matched by renewed political and economic efforts in Iraq.
