Note that we have made agreements to not weaponize space, so putting nuclear missiles in space would be difficult.
Not to mention that nuclear weapons in space is a cure that may be worse than the disease.
Furthermore, once you get to fractional-c levels of space technology, the defensive problem becomes much more difficult, and city-busting kinetic weapons turn into planet-busting.
If you have the basics that you need for to fractional-c levels of space technology I think you make a mistake by thinking that “space” is very important. With that kind of technology you can do damage in a lot of ways.
If you have fractional-c level tech for objects larger than very small mass accelerator gun rounds, things are entirely different and you can probably just make a damn nuke.
