"Russia tested a new long-range missile on Wednesday that should improve its ability to penetrate missile defense systems, the military said, in Moscow's latest warning to Washington over deployment of a missile shield in Europe."
"Russia and the United States are still in talks to agree cooperation on missile defense, but Moscow has warned of further measures if no such deal is reached and Washington refuses to provide binding guarantees its system will not threaten Russia.
At a conference in Moscow this month, senior General Nikolai Makarov said Russia could carry out pre-emptive strikes on future NATO missile defense installations to protect its security."
