US President George Bush (L) and Soviet counterpart Mikhail Gorbachev confer during their joint press conference 31 July 1991 in Moscow concluding the two-day US-Soviet Summit dedicated to the disarmament. Nine years of talks were successfully concluded 31 July when two heads of state signed START, the Strategic Arms Reduction Treaty which will cut the superpowers's nuclear arsenals by up to a third. The Soviet leader called the treaty "a moral achievement" which replaced "militarised thinking" with "normal human thinking". (Photo by MIKE FISHER / AFP) (Photo by MIKE FISHER/AFP via Getty Images)
