Be careful, because the ways around the law would be possible for your opponents as well. This plan in particular sounds like an excellent way to get murdered by sniper bullet with a simultaneous full spectrum EW attack to prevent a killswitch signal getting out. Possibly accompanied by simultaneous SM-3 attacks on whatever you have in orbit.

And this is just one of the many many ideas. You would also need near perfect infosec to make sure your orbital weaponry doesn't get stolen away from you and you are the biggest, shiniest target imaginable.
