original passage: Khrushchev sought to find a lasting solution to the problem of a divided Germany and of the enclave of West Berlin deep within East German territory. In November 1958, calling West Berlin a "malignant tumor", he gave the United States, United Kingdom and France six months to conclude a peace treaty with both German states and the Soviet Union. If one was not signed, Khrushchev stated, the Soviet Union would conclude a peace treaty with East Germany. This would leave East Germany, which was not a party to treaties giving the Western Powers access to Berlin, in control of the routes to the city. They propose making Berlin a free city, which meant no outside military forces would be stationed there. West Germany, United States and France strongly oppose the ultimatum, but Britain wanted to consider it as a starting point for negotiations. No one wanted to risk war over the issue. At Britain's request, Khrushchev extended and ultimately dropped the ultimatum, as the Berlin issue became part of the complex agenda of high-level summit meetings.
