EVERYTHING we use depends on satellites... all our new GPS-guided munitions, some of the Star Wars stuff, most of our current navigational and communications equipment... everything.
The Chinese don't give a damn what a bunch of hand-wringing politicians have to say, and they don't care wheteher they sent us a message or not. What they care about is developing weapons systems that work when they need something destroyed... rather than sending a message of compassion and dialogue.
But...but....China is our friend....aren't they?
