I know it makes miltitary sense but with our fervent national drive toward empire, I worry mightily when I read about things like operation counterspace. Do we really need a policy to wipe out other countries space assets just because we don't like others looking down on us? This document talks about wiping out neutral or friendly space assets if we *think* they are being used by adversaries against us (us being the U. S.A.).
I guess I take the position that its the job of the military to prepare for contingencies, and they'd be negligent if they didn't consider the possibilities. Ideally, one would like to continue to keep space arms-free, but that might be unrealistic considering what's going on elsewhere.
The main aim of the Chinese military right now seems to be retaking Taiwan, and they know that they'll need to take on the U.S. in order to do so via force. To that end, they've been practicing ways to sink carriers, and there's reports of Chinese anti-satellite and GPS jamming research programmes. From their perspective that makes sense, since the U.S. is their main obstacle from retaking Taiwan, and increasingly the U.S. military is relying on GPS to guide things like smart bombs & drones. Knock that down, and take out some spy satellites, and that evens the field quite a bit.
The US became an empire at the end of the Spanish-American War. We've just never been comfortable with the idea of being an empire as a populace.
As far as space based assets go, we're bound by a number of treaties to participate with other nations. Weather satellites and communications satellites come immediately to mind, but I know we also have some treaty obligations where some of the science satellites are concerned. I doubt we'd be shooting down *any* satellite without some very strong reason, since the debris would damage a lot of other satellites in similar orbits.
