President Trump (bottom right) announced that America would walk away from the Intermediate-range Nuclear Forces Treaty earlier this year, in a move which came into effect on Friday. The treaty was signed by Ronald Reagan and Mikhail Gorbachev (top) in 1987 and banned all-but the most powerful nuclear weapons, and was credited with putting a stop to the Cold War arms race between the United States and Soviet Union. America has accused Russia of violating the treaty by developing the 9M729 cruise missile (bottom right) and said that it needed to tear up the deal in order to counter that threat, and weapons being developed by China which was never a signatory to the treaty.
