One missile going into space will trigger every single ICBM warning system on the planet. Most of the world's great powers don't need to fire a missile into space to take out a satellite. They've already lifted that capability into orbit. I don't believe any of those powers would take out satellites willy nilly. I think it would take open direct military conflict. At the same time though, I didn't believe any of them would 'cross the Rubicon' with respect to undersea pipelines and internet cables either without direct open military conflict. So, yeah. Gonna be fun times in the future I guess?
