“As long as nuclear weapons exist, there is a risk that they could be used- by accident, via a technical failure, or though the evil will of a man, madmen or terrorists. A nuclear-free world is not a utopia, but an imperative. Yet it can be achieved only through the demilitarization of international relations.”

-Mikhail Gorbachev, speaking in Reykjavik, marking the 30th anniversary of the 1986 Soviet-American summit.
