If Israel strikes Iran, it'll be because Obama didn
You should read the whole article but here are a few excerpts I found interesting
Prime Minister Benjamin Netanyahu has dealt primarily with three things over the past three years: Iran, Iran, and Iran.
He hasn't forgotten for a moment that two leaders he happens to admire, Franklin D. Roosevelt and Winston Churchill, didn't lift a finger to save European Jewry during the Holocaust. He is convinced that U.S. President Barack Obama won't lift a finger to save Israeli Jewry. Thus he believes solely in the Israeli sword, seeing it as a deep expression and the last defense of the Zionist revolution.
As of now, the military option is proving to be a diplomatic success. It managed to shake the international community out of its apathy and made a definitive contribution to the tightening of the diplomatic and economic siege on Iran.
But the time for playing diplomatic games with the military option is drawing to a close. There's a limit to how many times one can cry wolf. There's a point at which a "hold-me-back" policy exhausts itself. And that's a very dangerous point, because suddenly the military option turns into a real option.
The Netanyahu-Obama meeting in two weeks will be definitive. If the U.S. president wants to prevent a disaster, he must give Netanyahu iron-clad guarantees that the United States will stop Iran in any way necessary and at any price, after the 2012 elections. If Obama doesn't do this, he will obligate Netanyahu to act before the 2012 elections.
The moral responsibility for what may happen does not lie with the heirs of Chaim Weizmann and David Ben-Gurion. The moral responsibility will be borne by the man sitting in the chair that was once Franklin Roosevelt's.
