According to The Guardian, it was going to be earlier this year, by US gave no support:

Quoting senior European diplomatic sources, The Guardian said Israeli prime minister Ehud Olmert raised the issue with Bush in a one-to-one meeting May 14.

Israeli sources, obviously, deny the whole story.

But, how long until Israel decide to attack without American support? As Robert Baer puts it,

Israel knows that international diplomacy against Iran up until now has been a farce. Iran called Bush’s bluff, ignored sanctions and continued its nuclear program with impunity. And if the Israelis needed another psychological kick in the pants, last week North Korea announced that it is back to building a bomb, likewise with impunity.

Finally, Israel has to calculate that American influence around the world is on the wane. Americans are tired of the wars in Iraq and Afghanistan. And now, after the war in Georgia, Russia is opening up its flow of weapons to Iran.

Couple all of this with Israel’s suspicion that Iran is within only a few short years of having a nuclear bomb, and Israel knows time is not on its side. It is starting to believe that it has no choice but to change its fortunes with arms.

It’s impossible not to remember the events of 1981, when Israel, with no warnings, destroyed an Iraqi nuclear facility.
