Why was Soviet leader Mikhail Gorbachev interested in ending the arms race with the United States?

"In February 1987, Gorbachev announced that the Soviet Union was willing to proceed with negotiations on the INF Treaty. This time, he suggested that “the problem of medium-range missiles in Europe be singled out from the package of issues and that a separate agreement on it be concluded, and without delay.” In other words, he was dropping his insistence on including SDI in the negotiations."

the best description of postwar writers might be progressive.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
