The list of things states have attempted to deploy offensively is nearly endless. Modern operations research arguably came out of the British empire attempting (succeeding) to weaponise mathematics. If you give a state fertiliser it makes bombs, if you give it nuclear power it makes bombs, if you give it drones it makes bombs, if you give it advanced science or engineering of any form it makes bombs. States are the most ingenious system for turning things into bombs that we've ever invented; in the grand old days of siege warfare they even managed to weaponise corpses, refuse and junk because it turned out lobbing that stuff at the enemy was effective. The entire spectrum of technology from nothing to nanotech, hurled at enemies to kill them.
We'd all love if states commit to not doing evil but the state is the entity most active at figuring out how to use new tech X for evil.
