Israel is defending its attacks on Hezbollah and Lebanon as self-defense. By itself, this defense is not controversial. Hezbollah agents entered Israel, killed Israeli citizens, and captured two Israeli soldiers. Few citizens of any country would object to the use of force by their own governments in a similar situation.
The two important questions, however, are the following:
1. Is the magnitude and nature of Israel's response in the best interests of Israel?
2. What U.S. policy is in the best interests of the U.S.?
Since I am not an Israeli, I do not take a stand on what Israel should do. As an outisde observer, however, my guess is that Israel's current strategy is not in its own best interests. Hezbollah is not being destoryed, merely displaced. This means Hezbollah can return to Lebanon or survive elsewhere. And since Israel's actions strike many Lebanese and others in the Middle East as excessive, the current attacks are an excellent recruitment tactic for Hezbollah. Thus Israel's chosen path is unlikely to produce long-term security for Israeli citizens.
On the question of U.S. policy, my view is that the U.S. should do nothing. Yes, I mean nothing. No visits by Condoleeza Rice to the Middle East. No statements supporting Isreal or criticizing Israel. Nothing. This is my view on all foreign policy issues unless events outside the U.S. have serious and imminent consequences for the U.S. The situation in Israel / Lebanon does not qualify.
