Nobody has wanted to use cryogenic liquid fueled rockets to kill people since rockets that weren't like that were invented. It takes hours to get one ready to fire which might have been worthwhile[1] for the first ICBMs in the era before satellite surveillance but any modern military would be crazy to use one. But if you're worried about launching military communication satellites, well, they probably will be at some point. [1] Not my view of what's worthwhile of course.
