Iran has no choice but to submit, the whole western world is after them and the zionist and Muslim zionists have a sword on Iranian neck. Iranian leadership must be realising all those big anti Usa and Zionist statements are finally hurting them, the economy is in shambles, airforce non existence, navy non existence, missile force is decent but failed to protect Iran during 12 days war and another war is around the corner. Iran as someone suggested is buying time but the western world also knows this, slowly they are tightening the noose.
The positive for Iran is China Russia have used some diplomatic pressure to defend Iran, Pakistan for some reason was being aggressive, so they have some support in this part of the world and have those who don't want Iran to be destroyed, the economic interests are another advantage. If only Iran is willing to tone down their aggressive stance to a diplomatic one, continue to work with international players on nuclear energy, then slowly win Chinese Russian support to remove sanctions, build a good military force to defend themselves. I can't see any other way out for Iran.
