A planned missile defence system to be deployed in the NATO region would directly threaten Russian national security and the Kremlin "strongly advises" Brussels not to go forward with it unilaterally, a senior Russian official said Monday, according to dpa. "Real strategic partnership would not be possible," said Russian Foreign Minister Sergei Lavrov. "Russia would have to respond." Russia's senior diplomat made the comments at a NATO-Russia Council meeting held in the Russian Black Sea resort city Sochi.
