I think they are closer to the truth than the armchair spies here.

We should not be deceived by Iranian posturing : Iran blinked and it is all Beacuse of economic sanctions and bleeding through the Syrian and hizb Allah engagement in the Syrian civil war . In order for Iran to move from the tactical to the strategic the sanctions must continue with no end in sight .Ultiamtely the Iranian elites are concerned about being in power , they are keenly aware of 2009 events ?Beacuse of the sanctions and Syrian bleeding , the modality words and Iran is on unsustainable path , the more sphere the better . The trajectory is clear , Iran will devalue its currency sometimes between the second anniversary of June real sanction regime and the end of the year , after that the economic state will become political and will cause the elite to differ among themselves .Hence Iran will be much weaker .The other thing to do selectively is to pick up their experts in science .. In maximumum two years Iran will buckle and come begging . The only risk is for Obama to lose his nerve
