Ok how would we have won either war? What tatics should we have deployed? Whe had over 500K soldiers in Vietnam so how could we have done more? Lets see how you wiggle out of this.
Our manpower/war toys were no match for the North - they could produce more soldiers than we ever could, and we were in their neighborhood. LBJ lied about VietNam - The Decider lied about Iraq. We never seem to learn. Have you visited the VietNam wall in DC to see the +57,000 names on the VietNam War Memorial black granite wall?
"...especially if Israel keeps pulling back everytime they are winning..." - they are not "winning", and they realize it. Lebanon and Israel will be the loosers.
