um... Astropolitik as a real geopolitical concept has existed since the Cold War. International Space Law exists and it has since 1967. The Moon Agreement was signed in 1979. Entire doctrines have been written in the 1990's and early 2000's. Satellites revolutionized warfare in the past 50 years and China's anti-satellite weapon tested in 2007 accelerated the development of Astropolitik and space doctrines.
