I fully agree that Iran will go nuclear...as will Saudi Arabia.
The SA-10 deal signed with Rostec Corp back in 2007 but put on hold in 2010 because of...UN resolution 1929. Hell, even Iran filed a $4 billion lawsuit in international court for breach of contract. So in Feb, Rostec's CEO (a former KGB buddy of Pootie Poo), offered Iran the Antey-2500 (an even more modern version of the SAM system offered in 2010) if they withdraw the lawsuit. Worth noting that Medvedev place a ban on missile sales to Iran but Pootie lifted that ban in
April.
Russian arms sales have ZERO to do with money and are all about foreign policy in the form of power projection (like pissing off adversaries via a friendly government). The US is talking about providing weapons to Ukraine so what will Russia do? Any bets whether there will be a Russian military base in Iran before the 5 years is up?
This nuclear deal really just solidified the Russian, Iranian, and Chinese alliance in the Near East and has nothing to do with business. Obama is focused on his library and legacy whereas our enemies are looking at more strategic targets (e.g. backing this deal, OPM database, etc).
Mr Chow, a possible Chinese "illegal", said it best when he jumped out of the trunk of the Mercedes in Vegas.
