If i were a head of state of some country, i would be making arrangements to get a satelite-killer weapon up there aswell. And pretty soon you wouldn´t be able to leave the damn planet because your ship would collide with one of the million space debris that would be floating up there...
Space should be weapon-free. If not, what´s keeping some other country from using the moon as a base for a satelite turkey shoot? Or worst.
I envision that in a near future every space-able nation will be placing a similar trinket up there, and then it will be a matter of time before the borders of each individual nation gets extended upwards, like a bigger national air-space. Wich wouldn´t be all that bad, come to think of it. Just how high does a country´s air-space goes, right now? 20km? 30? Just raise that to 3000 km, and we would be fine, as at that height you can´t keep a geo-stationary satelite without resorting to engines thrust.
On a side note, there is no need to have a nuclear platform up there, since chances are there is one already. And the russians have one too. They just don´t "advertise" that they do.
