it dosnt matter if iran has nukes or not.
china depends on iran, they will not allow anyone to attack them.
russia has already threatened us if we assisted the UN in attacking syria, and they are close to china and iran already anyways.
russia+china nukes = far far more then isreal/uk/us nukes.
this is about much more then iran, yeah iran is a joke of a conflict, its everyone else that the issue arises.
see, we cant attack a SINGLE iranian ship for any reason. or we answer to china and russia. everyone thinks iran is just attempting to force us into a war.
