Former Soviet leader Mikhail Gorbachev may be remembered today as the man who presided over the collapse of an empire: The recent anniversary of the fall of the Berlin Wall in 1989 saw major celebrations to mark the collapse of Communism in eastern Europe and the reunification of Germany.
President Ronald Reagan famously called on Soviet leader Mikhail Gorbachev to "tear down this wall" -- the Berlin Wall. But the wall actually came down early in the presidency of George H.W. Bush, in November 1989.
The Russian government has said it would be forced "to take measures" if the United States began developing new missile systems, ratcheting up the rhetoric after US President Donald Trump said he would ditch a Cold War-era nuclear arms treaty.
