As Russia sped ahead with the annexation of Crimea and the US drew up more sanctions to punish Moscow, American and Russian officials were last week working side by side in Vienna as if unaffected by the unfolding drama of the new cold war.
Emerging from a round of international talks with Iran on downsizing its nuclear ambitions, US officials expressed satisfaction that their Russian colleagues had acted constructively.
Moscow, said a senior US official, had no interest in Iran obtaining a nuclear bomb or in an escalation in tensions in the Gulf. Moscow takes part in the Iran negotiations for its interests, he noted, not those of the US.
