Shrewd, exceedingly ambitious, and willing to bend rules to get results, McChrystal was widely regarded as the most effective commander in the entire Army. Vice President Cheney and Secretary of Defense Rumsfeld held him in the highest esteem, considered him absolutely trustworthy, and regularly bypassed the chain of command to communicate with him directly. He worked under the radar and got stuff done. He didn’t suffer from “the slows,” as Rumsfeld characterized the risk-averse nature of some of McChrystal’s superiors.
