From around the blogosphere, we’re hearing reports again that Israel plans to strike Iran first with nuclear weapons. I have my doubts that Israel would do this, and I suspect this was leaked as a way to bolster the diplomatic effort underway to get Iran to give up it’s nuclear program. If you view it along side plans to move a second carrier battle group into the Persian Gulf, I think that’s the most likely scenario. Diplomacy without a real threat of military force is just a bunch of talk, and without it, the Iranians have no reason to concede anything to us.
But there are numerous tactical problems involved with an attack by Israel on Iran. Israel lacks the in-flight refueling capability to project power that far away from the Levant, and no Arab country would allow Israel basing rights to use for the attack. So I would be very surprised if these leaked plans are for real.
