“It’s politically sensitive, but it’s going to happen. Some people don’t want to hear this, and it sure isn’t in vogue, but — absolutely — we’re going to fight in space. We’re going to fight from space and we’re going to fight into space. That’s why the US has development programs in directed energy and hit-to-kill mechanisms. We will engage terrestrial targets someday—ships, airplanes, land targets—from space.”
~ Commander-in-Chief of US Strategic Command (1994-1996), Joseph W. Ashy
