What military force is the UN going to use against Iran, seriously? Economic sanctions and embargos would only work if all countries jumped on board, so what if the US won’t ship electronics to them. Im sure North Korea is not going to stop missile shipments. And what about Russian arms sales to Iran? In 2002 the Russians were accused of exporting arms to Iran which could have exceeded 400 million dollars. To already economically depressed countries, like Russia, stopping trade to a country with good cash flow, like Iran, will seem ludicrous.

I have a hard time believing that the UN with all its omni-potent powers would have any success enforcing trade embargos against Iran, and military action lies in the realm of the impossible.
