In orbit? Probably not. No country has operational satellites designed to attack ground targets. They would need to launch missiles or send drones.

In a total war you absolutely do target factories and industry. But this is easier said than done; they tend to be deep inside enemy territory. And drones are made out of commonplace consumer electronics parts, which could be made in thousands of factories around the world.

Why are you so sure of that? It would be very surprising if at least the United States and Russia didn't have orbital weapons. They've been in sending large stuff to space for decades.

Of course they wouldn't have told you or anybody else who isn't supposed to know.

And that's what you would do - or threaten to do - long before you start replacing your roads with tunnels as the author is suggesting.

Depends on what you mean by “orbital weapons”. I assume you are not thinking of the sidearms of astronauts, or anti-satelite satelites. If you are thinking about nukes pre-positioned in space then the 1967 Outer Space Treaty bans the stationing of weapons of mass destruction (WMD) in outer space. And this is not just paper prohibition. The reality of space based nukes is that the time between deorbiting and touch-down is so short that nuclear armed states would treat their launch (the time when they are placed into orbit) as an attack and launch in retaliation against the launching country. Basically if you try to sneak them into orbit and the enemy finds out about them you will be anihilated. This is just simple MAD doctrine. So the strategic balance which is preventing you from launching your ground based warheads is the same which is preventing you from launching your future space based warheads into orbit. > Of course they wouldn't have told you or anybody else who isn't supposed to know. I wouldn’t assume that you or me would learn about it. But it is almost given that the peer nations would figure it out. They spend considerable resources trying to figure out if you are doing this. And then they get MAD and your country is no more.

		No idea how actually efficient that would be even in theory. I guess it's not technical technicaly impossible, but would it really bring any benefit compared to launching possibly many more cheaper transcontinental rockets from earth were maintenance and control is definitely easier.
