USA is too entangled in Afganistan and Iraq that they have given up on bigger situation of Iran.
For CHINA, the Americans will not venture there, they need foot soldiers like India for it and Indians are too disunited and too weak to be able to protect themselves from Chinese missile launch (ICBMs). So it is now the SOFT warfare the ghora way, the way the native Americans were wiped out and all you have is their small icons that ghora's wear as fashion.
