What attacking Iran will do is prompt retaliation by Iran with substantial military support by both China and Russia. In fact Russia will most assuredly assist Iran in satellite early warning negating any surprise the US/Israel may be depending on. It is entirely possible, as in the Korean conflict, US aircraft and naval assets may face Iranian aircraft with pilots speaking both Russian and Chinese. The US and the rest of their unholy accomplices know this is more than just a possibility.
So why the continued threats against Iran when the evidence of nuclear weapons production (Weps of Mass Destruction) is non-existent and no matter what Iran says or does will not satisfy Washington or Tel Aviv.

Is the US deliberately seeking a confrontation with Russia and China?
Do these arrogant assholes in Washington believe they can bluff Russia into capitulation or to simply sit back and do nothing allowing the US and Israel start another war as they did in Serbia and Iraq?

Russia and China have vowed and informed Washington of such that it will defend Iran politically and militarily if US/NATO attacks Iran. One then can logically conclude that the US/Israeli/UK Axis is really baiting China and Russia. Does the US and the other New World Order accomplices now feel they can successfully defeat Russia, China and Iran? The Project for the New American Century spells out in detail that any perceived threat to the US's Global Aspirations must be attacked and defeated. The US appears to be the instigator of WW-III to fulfill the PNAC blueprint.

You are correct. I am also a Vietnam vet and I can clearly remember the same kind of moronic brass with the same attitudes. But don't stop with Mullen, we should get rid of McChrystal and all the rest of the boot polishers to this and the previous administrations.
Congress has really dropped the ball in regarding their delegated power to "make all rules for the government and regulation of the land and naval forces." Congress could have put a stop to this nonsense many years ago if they had the balls.

Mullen is in dangerous territory and definitely out of his pay grade when he threatens Iran or should I say bluffing, . He and others should mind what they say as Iran just may call his bluff and raise him a preemptive attack.
