General Peter Pace, as Chair of Joint Chiefs of staff was doing a pretty good job of keeping the crazies corralled:

"There have been many other hints of military disaffection from plans to attack Iran--indeed, military resistance may help explain why, despite years of rumors about Bush Administration intentions, such an attack has not yet occurred. A Pentagon consultant told Hersh more than a year ago, "There is a war about the war going on inside the building." Hersh also reported that Gen. Peter Pace had forced Bush and Cheney to remove the "nuclear option" from the plans for possible conflict with Iran--in the Pentagon it was known as the April Revolution.

"In December, according to Time correspondent Joe Klein, President Bush met with the Joint Chiefs of Staff in a secure room known as The Tank.

"I am disappointed that circumstances make this kind of a decision necessary. I just think a divisive ordeal at this point is not in the interest of the country or the men and women in uniform or of the individuals," Gates told reporters. "But I think it's a realistic appraisal of where we are ...

Adm Michael Mullen, who took over as chairman of the US Joint Chiefs of Staff three weeks ago, said diplomacy remained the priority in dealing with Iran's suspected plans to develop a nuclear weapon and its [alleged] support for anti-US 'insurgents' in Iraq. But at a press conference he said: "there is more than enough reserve to respond (militarily) if that, in fact, is what the national leadership wanted to do". from:
