> What if countries decide to extend the airspace to the aerospace This is basically unthinkable. Attempting to knock down all the satellites that ever fly above your country would mean knocking down every non-geostationary satellite that ever reaches your latitude (or any latitude farther from the equator than you). Satellites are a key part of how we all know if anyone else is launching nuclear bombs or doing anything else so stupid. In the event that a country tried this I would expect that the foreign reaction would be very extreme. In the event that a country succeeded I would put the odds of nuclear war at above 50% and of conventional war at near 100%. On the flipside you might almost get away with knocking down a few satellites with relatively minor reactions (at least compared to war, and if you had some good justification), as long as you don't try and knock them all out...
