yeah... Nuclear warfare would practically be the apocalypse... I mean, imagine all the countries, shooting off all of their nukes. Millions and millions of innocent people would die. Im guessing the ME countries are not permitted to use them because there are terrorists and such in those places(not racist). And, if only one of those people gets their hands on this, chaos will ensue. Also, I dont think countries there will ever find it necessary to use nukes for defense. A nuke is fired really far away. And has a massive blast radius. If a country is being attacked, a nuke is not a very smart thing to use when the enemy is practically right outside the gate.
