The scuttlebutt for months has been that Prime Minister Netanyahu is still in the process of making a decision on whether to to attack Iran's nuclear facilities.

But Israel's Channel 2, quoting an American government official, says that he has already made up his mind to strike:

Channel 2 in Israel, sourcing a "senior American official", says that the decision has already been made by the Israeli government to attack Iran's nuclear facilities.

"All U.S. intelligence officials are confident the Israeli leadership has already decided to attack Iran, unless a significant change happens in the coming weeks or months with  the Iranian nuclear program," Channel 2 reports.

The report comes just hours ahead of Israeli Prime Minister Benjamin Netanyahu's speech to AIPAC in Washington.

AIPAC is the American Israel Public Affairs Committee and is widely considered the most powerful pro-Israel lobby group in the United States.

"A senior official stressed in a conversation with News 2 there is a dispute between Israel and the United States on the question of 'day after', which means the price of attacking Iranian nuclear facilities," Channel 2′s report says.

This is logical and plays into the notion that it was always unlikely that Netanyahu would not inform his most powerful ally that Israel was going to use force with Iran. Coordination "the day after" is going to be vital as Iran will almost certainly retaliate in some way and the two nations must plan for any eventuality.

Iran has announced a willingness to negotiate. Despite the virtual guarantee that those talks will fail, Netanyahu will probably wait until all peaceful options have been exhausted before striking.
