Sooner or later Israel will have to bomb Iran. Better sooner, because Iran is quickly approaching Israel's red line. Since intelligence is never precise, why wait 'til the last minute?

Summer and early fall is the best time to attack because that's when the sky is the clearest.

Israel is committed to destroying the S-300 missile defense systems should it arrive in Syria.

Close to 5,000 Hezb'allah troops, if not more, are now fighting in Syria. Thus they are concentrated which makes their destruction easier. Also they are no longer guarding their missiles stored in Lebanon with full force. Israel could call for a mobilization due to perceived threats from Syria. Then it could mount an all-out ground attack on the stockpile of missiles in Lebanon. The Sunnis in Lebanon including the Lebanese government will probably stand aside and let Israel solve their Hezb'allah problem. Israel could then go east and destroy the Hezb'allah troops.

Hamas would stay quiet because it is in Qatar's interest and Turkey's interest that they do so. Qatar and Turkey would love to see Israel destroy Hezb'allah because that would aid their efforts to bring down Assad. Obama would like that too. It would take the pressure off the US to act.

It would be nice to get Hezb'allah out of the way for when Israel attacks Iran. Saudi Arabia and Qatar would be supportive.
