Israel should make an agreement with the United States that it will not attack Iran if the U.S. Congress passes a defense treaty with America and the President signs the treaty that states that any attack on Israel is an attack on the United States. This should allay the fears of the Israelis because a treaty must be adhered to irregardless of who the President is. The U.S., Britain, France, and Germany should also offer Israel membership in NATO provided Israel seriously negotiates an end to the Palestinian Israeli conflict. Other than Turkey, every other NATO member would allow Israel to be part of NATO.
