An US attack on Iran is almost as true as the fact that the sun will go up tomorrow FlyingFrog. Why? Because that would put the allies to US in a possition where all Arab nations rather would help the Iran regime then to support the US. Israel is the arab nations traditional enemy number one with one exception and that is Turky, there are some courtesy thinking behind all wars conducted in the middle east. US aswell as Europe are not up for an outburst from the OPEC organisation and the oil the power from the black gold are influencing the world community who has turned against the disturbances in Sudan.
US, even if they probably got the worlds most powerful army they can not fight the whole region for themselves even with Brittish support they would make the whole world go back to another stone age if they conducted military actions togheter with Israel in aggression towards Iran. Even when US had support from the UN in the 1991 Gulf War when they liberated Kuwait togheter with saudi and other arab nations the big fear was that Israel should be involved in the fights against Saddam Husseins forces in Kuwait and in Iraq with eather the Israeli airforce or ground units.
That would have made that war nearly impossible to carry out. And todays date - You find highly sophisticated western equipment in all of those countrys that would turn there anger towards US and GB if Israel would get involved. For some examples. You can find over 400 IFV in the c.o US 30% and GB 70% built Desert Warrior vehicle only in the United Arab Republic. You find state-of-the-art Challenger tanks in Saudi Arabia and Patriot missile defenses all over the place.
The main US strategy for the middle east has always been to not make any arab nation bigger then the other. And localy disputes has always saved the balance in that specific region, and an Israeli co US attack on Iran would probably be the only thing that would make all arab nations to put away there local differences and attack togheter in a joint operation, If that happend US and its allies would be in a world of pain. However US have started successful military coups before against Iran and war is maby not the first solution for the Iran problem - it is more likely an emergency solution if Iran doesn`t attack the US first that is. In a military coup the world community would support the US and later the UN would go in much faster then in this Iraq war. Israel would not be involved in any of these actions.
