the problem with irbms is they are in a middle area where they're small enough to sneak around and setup in an enemies blind spot like a tactical nuclear weapon, but big enough to carry nation-wrecking warheads like the big nukes. so you've got a (potentially) nuclear warhead coming at you with less than 10 minutes till impact, you have no idea who's actually attacking you cause they snuck it onto a farm in rural canada or khazakstan respectively, and it's big enough to flatten the entire dc metro beltway / greater moscow district. your only options are die without a whimper like a cuck, or launch your total nuclear payload at every single one of your adversaries cause you don't know who did you dirty, or maybe you just pick the one you are the angriest at right now. they respond in turn, and voila, everybodys dead and the worlds a nuclear shithole, yippee. so yeah, they agreed to ban irbms back in the day for very good reason.
