Russia said on Friday Washington's new missile defense strategy would lead to a dangerous arms race in space and amounts to a relaunch of the Cold War-era "Star Wars" program. U.S. President Donald Trump on Thursday unveiled a plan which called for developing space-based sensors to detect incoming enemy missiles and exploring space-based weapons to shoot down missiles, among other steps to shield the United States. In a statement, the Russian Foreign Ministry described the U.S. plan as confrontational and said it would deal a blow to already-fragile international stability. The ministry urged Washington to engage with Russia in constructive talks about the nuclear arms balance "before it's too late".
