Russia Ready to Sell Anti Aircraft Weapons to Iran

Putin did not let any grass grow under his feet when the dust finally settled on the "framework" of a nuclear deal with Iran.  He was first in line to begin trade, presumably after sanctions have been lifted, and his first choice is a weapon that makes it difficult to overfly Iran for any purpose, including verification of the Iran nuclear deal.  

The weapon is the S300 which you can get a more detailed description of at [ http://www.bbc.com/news/uk-22652131 ].  It's range is 93 miles and an altitude of 17-19 miles.  It sets up in what is probably longer than the 5 minutes it is advertised.  The BBC says it is the equivalent of the Patriot missile.  The Russian RT news network says it is no longer being made and will be replaced by the S400.  The Russians have sold quite a few of them to various countries in the Middle East and, under pressure, backed out of deal to sell them to Syria in 2010.
