What If? Worlds
After the conclusion of the Second World War, General Robert Savage speaks to the newly formed United Nations, and stresses the importance of not only a world diplomatic force, but a policing force. The General is placed in command of the UN's security forces, which are named G.I. Joes by the people. Joe takeover was gradual, with them slowly gathering up power. Temporary emergency powers somehow become permanent, and keep growing. Under the Joes, peace is maintained and strengthened, and even though there are still seeds of discontent, the Joes faithfully and honorably defend the principles of peace and justice. In 1982, Joe science teams uncovered the Ark and studied it without waking the Autobots and Decepticons inside, using the technology they found to give the United States a huge technological edge. They use this edge to enforce their will across the world.
