[quote=@MetalLover] No law against it, but if you use them, you shall be punished by the international community. [/quote]That sounds almost like there's a law against it. Nukes, like everything, is just a weapon. A powerful weapon but if not used to massacre cities then that's all it there's about it. BTW, are depleted uranium rounds banned? Currently there's a potential for this because their use in hypervelocity projectiles effectively makes them like a chemical weapon. [quote=@FacePunch] I'd imagine you wouldn't want to use your nukes for anything. They ruin the country they're launched into making conquest impossible, and you open yourself up to being nuked by that nation or its allies. The only reason to ever use them would be because someone else did, or you want to destroy the entire planet in a massive nuclear war. [/quote]You overestimate the power of nukes. We can drop thousands of nuclear weapons on Earth and it barely changes anything. Actually, in the name of nuclear tests we already did. Btween 1995 to 2053 the nations through the world performed 2053 nuclear tests. That is, dropping 2053 nukes on Earth, lead by the USA to a considerable degree. Sure, megaton yield tests were just a tiny percentage of those but so are the ratio of megaton warheads in comparison to the rest. Radiation poisoning is an issue but people live in Hiroshima even now and did even some years after the bombing. And since I talk about clean nukes (no radioactive material is left on the site to contaminate the area) this issue is practically null, too. Nukes are also nothing really close to apocalyptic. Their capability to destroy an entire city (in case of higher yield strategic warheads) is terrible but you would need billions or even more nuclear warheads to ever cover the surface of Earth with them. Another note is that since countermeasures improved drastically the chance of successfully landing a nuclear warhead is diminishing unless somebody goes out of his way to launch insane amount of them at once. If anything since in WW3 nukes were used it'd clear away some if not all of the overexaggerated fear of them. Make no mistake. Nukes are powerful. A strategic nuke used in population centers can exhaust all war crime offenses you can think of in almost any conventional wars and do it at once. But annihilating a nation? At best in figurative sense by eliminating their governing body and key industries. If the USA would ever turn into a crazy omnicidical nation their current stockpile is barely enough to literally annihilate a smallish nation like my country. So yeah, use of strategic nuclear warheads on cities is practically equal to a war crime. Using tactical warheads in battle? With the radiation poisoning removed it could be a matter of escalation. If a nation is pushed enough they could try that against an enemy army. It'd be somewhat comparable to using chemical weapons in WW2 though. You give the authorization for the enemy to use their own tactical warhead stockpiles to use against your army (or even your city centers if they don't realize they would be overstepping their boundaries).
