Thus, unlike Israel’s air strike against Iraq’s reactor in 1981 or Syria’s in 2007, both of which were planned in the utmost secrecy, the Israelis have gone out of their way to advertise their fears, purposes and capabilities. They have sent warships through the Suez Canal in broad daylight and conducted widely publicized air-combat exercises at long range. They have also been unusually forthcoming in their briefings with reporters, expressing confidence at every turn that Israel can get the job done.

The problem, however, is that the administration isn’t taking the bait, and one has to wonder why. Perhaps it thinks its diplomacy will work, or that it has the luxury of time, or that it can talk the Israelis out of attacking. Alternatively, it might actually want Israel to attack without inviting the perception that it has colluded with it. Or maybe it isn’t really paying attention.

But Israel is paying attention. And the longer the U.S. delays playing hardball with Iran, the sooner Israel is likely to strike.
