After a certain point in the plot, you get the ability to build nukes, supposedly as a deterrent against other people invading your FOBs. Around this point, you also get the ability to completely ignore other people's nukes and invade them anyway.
Is there any circumstance under which one of these nukes would actually go off? Can I actually nuke people who mess with me? Or perhaps sneak into wherever a rival is keeping their nukes and rig one to blow?
