Why Russia's Changing Its Tune on Iran

Russia has been sending some confusing signals on Iran in recent weeks. Rumors began to circulate that Russian President Vladimir Putin would be heading to Tehran to meet with newly inaugurated President Hasan Rouhani—with some even predicting that Putin would "drop in" on Iran this week after completing his visit to Azerbaijan to confer with Azeri President Ilham Aliyev. Stories were also released that Russia was reconsidering its unilaterally imposed boycott on selling advanced S-300 air defense systems to Tehran, or at least replacing them with another variant, the Antei-2500 system, as a way to get Iran to drop its legal action at the International Court of Arbitration in Geneva that charges Moscow with breach of contract over the S-300s.
