Let's hope they don't have a nuke wielding lunatic in a mobile suit and also they could've made way worse weapon or example there's this really god trilogy of SEED fics and in the third one a group called F.E.A.R makes a type of nanoweapon called MAIDEN which kills anything that isn't human or coordinator by setting it on fire like napalm THEN they used construction nanotech called red EDEN (which is completly harmless to living beings and has large limits like no self replication/grey goo incidents and can only rearrange molecules and atoms) to to create more MAIDEN out of the corpses of their enemies and this was their more "ethical" creations.ALL THE CRITS...
We just kept getting crits and completely mucked up their trap in the process...
