Russia will be forced to make a military response if the US-Czech missile defense agreement is ratified, the Russian Foreign Ministry said Tuesday. The statement came hours after US and Czech officials reached an initial agreement on deploying elements of a missile defense system in the Eastern European country. Russia said the system would severely undermine European security balances by weakening Russia's missile capacity. If the agreement is ratified, "we will be forced to react not with diplomatic, but with military-technical methods," the Foreign Ministry statement said. It did not give specifics of what the response would entail.
