Appeasement will not resolve the humiliation issue. Hamas will see it as a victory and embolden itself. And the Israelis will have more fear because of the people let loose. He is right in a different way however. Confrontation and isolation haven't worked. The way to pressure Hamas is with Compassion. Offer to negotiate with them. Don't give in on what you want, but be willing to negotiate. If Hamas refuses, Israel wins. If Hamas accepts, Israel wins. Do not give in, but negotiate.
