From Carolyn Glick, who was never fooled by the Obama administration:
If the Palestinians follow through with their threat to renew their terror war against Israel it will be quite bad. This is so not because Israel will be unable to defend itself. Israel has the means to defend itself. It will be quite bad because, in light of the hostile treatment Israel is suffering at the hands of the Obama administration, and given the central role the U.S. under Lt. Gen. Keith Dayton is playing in arming and training the Palestinian army that will likely be attacking Israeli targets in Judea and Samaria, the U.S. may well side with the Arabs against Israel. The administration is already placing limitations on arms sales to Israel. In this event, Israel will have to move quickly to find other suppliers.
It is unlikely today that Arab states will go to war with Israel, although that could change quickly if Iran acquires nuclear weapons. In that event, the Iranians will be in a position to blackmail Arab states like Egypt and Jordan into abrogating their peace treaties with Israel and opening hostilities against it. Iran would accomplish this task by threatening to overthrow the Mubarak regime and the Hashemite Kingdom. It is this specter — along with the specter of nuclear attack and chronic terror violence conducted under Iran’s nuclear umbrella — that makes it essential for Israel to move quickly to prevent Iran from acquiring nuclear weapons.
LOPEZ: How nervous is Israel about Ahmadinejad’s “reelection”?
GLICK: In a round about sort of way, Ahmadinejad’s “reelection” empowers Israel to take the necessary action. By stealing the election, Ahmadinejad now stands in open opposition to the Iranian people. This decreases the likelihood that the public will rally around the regime in the event of an Israeli strike against Iran’s nuclear installations.
Ahmadinejad’s open hatred of the U.S. and his humiliation of the Obama administration will similarly make it more difficult politically for the administration to prevent Israel from striking Iran. If before the Iranian elections it was easy to see the administration signing on to U.N. Security Council sanctions against Israel in the event of an Israeli strike against Iran, or even shooting down Israeli aircraft en route to Iran, in their aftermath, such prospects seem more unlikely.
Emphasis mine. I wish that it were unthinkable, but it’s not.
