I do NOT think Iran is dumping dollars because we are strong arming them.

I DO think their financial ministers are (much the Saudi government did in the late 70's when their decision to convert their dollars into gold causes a 550% spike in gold prices) seeing that the value of their petro dollars is decline and they just don't want to hold or trade for them anymore.

If they loved us (as Saudi Arabia's government does now) they might STILL be making this decision.
