I think John Bolton and the administration have made clear that we'll take away nuke capability from iran, whether there are sanctions or not. The russkies are bluffing, now. The muzzies have put their faith in leftist lies and worthless promises.
The Russians are scared to death of the Muslims in their midst. It is interesting that the Tataristan cleric is mouthing off. He is bought and paid for by the Saudi Arabian wahhabists (who used Tariq bin Laden to begn their nfiltration of the Soviet Union in 1990).

Its major endeavor has been the construction of the Russian Islamic University in Kazan, the capital of Tataristan itself.
