But in international diplomacy as in domestic political life, we must follow the wisdom of William F. Buckley and take the world as we find it — and not how we wish it to be. And the reality on the ground in Gaza is clear to all.

The prolonged killing of children and women in Palestinian territories will only serve to weaken Israel and strengthen Hamas. Tragically, this comes at a time when Hamas leadership was on the run, hated at home and isolated abroad. Every day that goes by with images of children being pulled out of the rubble of bombed-out schools, hospitals and public markets is a day that only makes Hamas stronger and threatens Israel’s long-term security.

That is bad for Israel, bad for America and bad for Middle East peace.
