But Hamas is not just a terrorist organization. Hamas is an idea, a desperate and fanatical idea that grew out of the desolation and frustration of many Palestinians. No idea has ever been defeated by force — not by siege, not by bombardment, not by being flattened with tank treads and not by marine commandos. To defeat an idea, you have to offer a better idea, a more attractive and acceptable one.

Thus, the only way for Israel to edge out Hamas would be to quickly reach an agreement with the Palestinians on the establishment of an independent state in the West Bank and Gaza Strip as defined by the 1967 borders, with its capital in East Jerusalem. Israel has to sign a peace agreement with President Mahmoud Abbas and his Fatah government in the West Bank — and by doing so, reduce the Israeli-Palestinian conflict to a conflict between Israel and the Gaza Strip. That latter conflict, in turn, can be resolved only by negotiating with Hamas or, more reasonably, by the integration of Fatah with Hamas.

Even if Israel seizes 100 more ships on their way to Gaza, even if Israel sends in troops to occupy the Gaza Strip 100 more times, no matter how often Israel deploys its military, police and covert power, force cannot solve the problem that we are not alone in this land, and the Palestinians are not alone in this land. We are not alone in Jerusalem and the Palestinians are not alone in Jerusalem. Until Israelis and Palestinians recognize the logical consequences of this simple fact, we will all live in a permanent state of siege — Gaza under an Israeli siege, Israel under an international and Arab siege.

I do not discount the importance of force. Woe to the country that discounts the efficacy of force. Without it Israel would not be able to survive a single day. But we cannot allow ourselves to forget for even a moment that force is effective only as a preventative — to prevent the destruction and conquest of Israel, to protect our lives and freedom. Every attempt to use force not as a preventive measure, not in self-defense, but instead as a means of smashing problems and squashing ideas, will lead to more disasters, just like the one we brought on ourselves in international waters, opposite Gaza’s shores.
