The Washington Post reports the Palestinians and the Israelis are both unwilling to compromise for peace, or even a cease-fire. Talk about a non-story, did anyone paying attention not know this already?
To date neither side has taken enough punishment to want to quit. The Palestinians think they're winning in the court of world opinion, and they may be correct.
The Israelis know there are still Hamas weapons, tunnels, and infrastructure they haven't destroyed. They see no reason to stop until they achieve their goal of disruption and chaos.
The Palestinians asked for this war, and we need to let them enjoy it. The Israelis used Hamas rockets as adequate provocation to invade Gaza to take care of business, and we need to let them get on with it.
Fighting in the Holy Land will stop when the two parties are ready for that to happen. Or, until one side manages to exterminate the other - not a likely outcome. The U.S. has no meaningful role there.
