The center of gravity of American military power is in space. Everything from navigation to communication to intelligence satellites operate in space. If any power were to knock out the United States, it would have to knock out those assets. If the Japanese and Turks were to take on the United States, that would be the place they would have to strike first, to blind us, to cripple us. I would expect the war to start there. It seems like science fiction, but one wonders how somebody in 1900 would have felt about a description of what World War II was going to be like.
