Churchill continued to lead the Conservative Party and, for six years, served as Leader of the Opposition. In 1946, he was in America for nearly three months from early January to late March. It was on this trip that he gave his "Iron Curtain" speech about the USSR and its creation of the Eastern Bloc.
