The only way to respond is early warning or automated response. Early warning comes from space based systems. Automated response results in mistakes from spoofs.
I know we will come up a response, but weapons escalations are interesting to watch.
They definitely are interesting. A little terrifying but definitely interesting. What happens when the world you live in isn’t big enough for the weapons you have? :-)
We are not there yet but at some point SOME of the weapons created will be of more use for battles between planets than countries
