Moshe Dayan.
Even though he made a HUGE tactical mistake in handing over the Temple Mount to the bandits who defiled it.
Dayan was brilliant in '67, but was wobbly in '73 as Meir's defense minister. Sharon argued crossing the Suez over Meir and Dayan's objections. Sharon eventually got his way and brought his tanks and troops within 50 miles of Cairo until the Soviets and Americans pressured Israel to halt. The entire Egyptian 3rd Army was surrounded at the time.
