You're being too hard on Eisenhower. He had to deal with a bunch of Prima Donnas in Montgomery, Patton and De Gaulle and the various allied politicians. Patton was lucky to retain his command after the slapping incidents and Eisenhower and Bradley went out on a limb insisting that Patton assume command of the Third army. Eisenhower wrote at the time
"If this thing ever gets out, they'll be howling for Patton's scalp, and that will be the end of Georgie's service in this war. I simply cannot let that happen. Patton is indispensable to the war effort – one of the guarantors of our victory."
Ike was still an idiot. He didn’t do many favours for the country. Not many have.
