Nuke us? Do you think that they actually want to commit suicide?
Do you really think that our Muslim loving president would do anything about it?
If Iran nuked us?
Yes.
I know some right-wing nutcases such as yourself like to believe that Obama is some sort of boogeyman who wants to suspend the constitution and declare himself as dictator for life like some sort of new Stalin but all things said and done...Obama just doesn't have the balls to be Stalin. Obama I am glad to inform not matter what your Alex Jones fueled fantasies tell is not even an independent agent there is nothing ever does that is not approved by people he is beholden to, so even if Obama were to be a Muslim lover the people he is beholden to would make sure he would answer Iran in kind if they ever were to "nuke" us. You see in your childish myopic view of the world you might be of the sort who thinks just because politicians are in the seats of power that they are the actual wielders of power but nothing is further from the truth. The only power that our politicians wield is the illusion of power. But in truth it is all smoke and mirrors like the Wizard of Oz.
You see the people who have the actual power are in it for their own self-interest and if you for one minute think that they would let a puny little power like an Iran or an Obama or a Republican congress fuck up their self-interest then you are one of the most gullible persons on this planet. Of course there would be a retaliation because the powers that be would demand it. If a person like Obama were fuck up and not retaliate then him and his party would be removed from the little power the wield as quick as you could blink.
