Iran and Israel

Roger Cohen makes some good points:

What’s really at issue here is that neither Israel nor the Arabs want a change in a status quo that locks in Israeli regional military dominance and the cozy relationships — arms deals, aid and all — that U.S. allies from the Gulf to Cairo enjoy.

American interests are, however, another story. They are not served by having no communication with Iran, the rising Mideast power; nor by the uncritical support of Israel that has allowed West Bank settlements to grow and peace to fade; nor by relationships with Arab states that comfort stasis.

Frankly, is Iran the real threat in any case?
