Analysts say the harsh Russian line could undermine President Obama's "reset" policy of making concessions in order to establish practical cooperation with Moscow, at a time when it is already under withering fire at home from Republicans who argue that Mr. Obama has already given away too much to the Kremlin with little to show for it in return.
Medvedev said that unless Obama signs a clearly worded and legally-binding statement declaring that NATO's anti-missile weapons will never be used against Russia, he will have "no choice" but to go ahead with Russian countermeasures, which would include stationing medium-range Iskander missiles in Russia's western enclave of Kaliningrad, from where they could rapidly strike NATO facilities across Europe.
"If our partners show an honest and responsible attitude towards taking into account Russia’s legitimate security interests, I am sure we can come to an agreement," Medvedev said. "But if we are asked to ‘cooperate’ or in fact act against our own interests it will be difficult to establish common ground. In such a case we would be forced to take a different response."
"If the situation continues to develop not to Russia’s favor, we reserve the right to discontinue further disarmament and arms control measures," including withdrawal from the New START treaty, he added.
