In 1968, McGee wrote "The Responsibilities of World Power", which warned against isolationism and urged the United States to accept its power and position imposed upon it in the aftermath of World War II. The book further argued that the U.S. had a responsibility to be a Pacific power, to act as a counterweight to China, and to support free nations in their efforts to remain nonaligned or western allies but not to fall into the Communist fold. The work was nominated for a Woodrow Wilson Foundation award.
