I wouldn’t be surprised if back in the Grenada/Panama era of the 80’s that there may have been many chomping at the bit. These days, I’m guessing not so much.
As to Iraq and WMDs, you could prob call him a “stooge” if you wanted to. But the little I know from a distance, that was something that racked his conscience for the rest of his life.
Grenada, they never had time to think about it - it took three days for the most mighty military in the world to secure one of the tiniest nations in the world.
After 9/11, Rumsfeld asked the Army for their plans. They gave him a stack of plans on occupying Afghanistan and requirement for 600K troops (per doctrine) - they had no intention of volunteering. He was furious to be sidelined when the CIA guy convinced W it could all be done with small teams and airpower.
For Iraq, Rumsfeld agreed to all their plans and they saluted happily when he said to not make any occupation plans...
War is ultimately a political endeavor; the goal of a war is to compel, by use of military force, some sort of political objective. It only makes sense then that the person in charge of directing when and where that military force is used is also the person who is empowered to carry out the political policy of the entire country.
For people who rise to the top of the military from within, every political problem becomes a nail in want of the military hammer for a solution, and thus the default answer to every crisis tends to become war. The Cuban Missile Crisis was defused without a war because both Kennedy and Khrushchev couldn't bring themselves to push the button marked nuclear war, while virtually the entire military establishment was convinced, and forcefully arguing, that the only way out of the situation was to be the first to push that button.
