McCain is a graduate of the US War College--the equivalent of a PhD in "warrior." He knows that wars aren't won by air forces, naval forces, bombs and missiles. Wars are ONLY won by troops on the ground occupying the enemy's territory. Throughout history, no force has ever defeated another force by dropping bombs on them, with the possible exception of atomic bombs in WWII, and that was only after occupying hundreds of islands along the way. McCain's denial of boots on the ground demonstrates his total ignorance or willful lying.
