Another scenario: Israel will provoke Syria to get Iran to interfere and when Iran hits Israel, the US administration (Republican or Democrats) will be obligated to defend Israel and the US public will support it whatever is te price! The US will not land on Iranian soil. I repeat, the US will not invade Iran! It will be hit hard, it will take it years just to repair its infrastructure!

If the united states will argue that Iran is supporting some of the Iraqi attacks on their soldiers , the question is : what are they (americans) doing there?
Is Iran fighting Americans in Florida? or New York ? They are fighting them in their region .
How will the united states response be if Iran occupied Canada ? and is threatening their national security ?
If Iran did not help us (lebanese ) in the past decades , Israel would still be in Lebanon , but I guess Israel was in the south, not in Beirut and Ashrafiyeh and Tripoli.

NONE of it has come to fruition.

Rationality says that Iran will get bombed if it does something that warrants it. But so far it has managed to get others to do its dirty work

1. The attack would be pretty ineffective if Iran anticipates it and prepares for retaliation. Any attack would have to be completely unexpected and entail a complete destruction of all of Iran’s infrastructure rendering it incapable of retaliation. In addition to it being a military tactic, there is a big political motivation for the need for both a ‘surprise’ and ‘fully destructive’ attack. The US has to protect its gulf allies (OIL SUPPLIES), its bases in these countries and Israel from retaliation.

2. The political will for military action is non-existent. It would be a political disaster to go to war when two senior administration officials are against it. Not that George Bush and his administration has anything to lose(he’s already going down in the history books as one of the worst US presidents) but the chances of a Republican win in November will be close to zero if an attack happens before then. Also, congress wouldn’t approve and if Bush doesn’t ask for permission then it’ll be disastrous politically.

3. Israel would have to prepare for a two-front war against Hamas and Hezballah. And the US will have to deal with Iranian proxies in Iraq (Mehdi Army).

Eventually I think a strike is bound to happen. If McCain wins in November he will probably find a reason to strike at some point. If not then Israel will when Iran gets too close getting its first bomb. No matter what the consequences of striking Iran are the consequences of a Nuclear Iran are worse. It is only a matter of political will and any smoking gun (fabricated or not) or reason to do so. If Obama wins then we will enter a period of appeasement that will have devastating repercussions years down the line.
