A Russian "Greenlight" to Attack Iran?

That is one intriguing interpretation of today's disclosure that Iran would be getting the long range Russian surface-to-air missile system known as the S-300PMU-1 (SA-20), and that the system would be deployable in as soon as six months from their expected September arrival.

The Russians no doubt relish the contortions the West is going through over Iran's nuclear program, but at the same time, their intelligence organizations are telling them that Iran is working on developing nuclear weapons and missile technologies that can also threaten Russian interests.

By selling the Iranians advanced weapons systems and then disclosing their most likely deployment dates, the Russians are trying to have their cake and eat it too.

They've outlined the outside window of Iran's greatest vulnerability to an air assault on its nuclear program and command and control facilities. It only remains to be seen now whether or not American and Israeli leaders will strike with enough force to irreparably destroy key elements of the Iranian nuclear program, or if they will make the deadly mistake of trying to avert a nuclear war "on the cheap."
