I know more about the north Korean theater then you, it is no where like that, plus they are poorly trained compared to the ROK for instance. A nuke allows their poor training to never be noticed in conflict.For the same reason it always did: another war in Korea would be an awful bloodbath that would leave thousands of US servicemen dead and decimate South Korea. Between Korean fortifications in the mountains, their large military (that persists despite acquiring a nuke - again) and high likelihood of Chinese volunteers infiltrating the theater in small army groups, it's just not worth it, nuke or not.
Iran hasn't had a nuke for decades. If US was serious about invading a country three times the size of France and 80 millions of population, it would have done it ages ago.
The truth is that, again, nuke or no nuke, invading an occupying Iran would be a terrible bloodbath for very little gain.
Much easier to dickwave across the strait.
What part of US military's tenfold growth compared to pre-nuke times looks like "careless" to you?
Right now, after all the post-Cold War cuts and terrific innovations, US military is four times the size compared to 1920s or 1930s.
That we know of. I am almost positive Iran has nukes, that is without me even looking it up, and should Biden get elected we most likely will go to war with Iran.
Nukes would prevent us from doing anything against them and they can constantly keep biting us in the heels knowing we wont do shit to them. Look at China and Russia for instance during the Obama admin.
It is almost like the population grew and we had three or four times of conflict since then? It is careless, as training has grown less like the old days and is more relaxed, is more like a country that knows they have a way to never be harmed or invaded because of its nuclear dterence. One that is pulling out of its conflict zones and may be permanent as watchers instead of invovled.
Had Iraq or A-stan had nukes we would never had gone in there. We only got Bin Laden because we had stuff that got them into Pakistan without being caught, Pakistan is a nuclear power, we could not invade to deal with them for that reason.
Think of this, had we nuked china during the Korean war, we could have changed warfare in such a way that using nukes to help win wars early on would be a common tactic. Something we would not want. Nukes have become a deterence because of its power and the death it brings. Take away nukes and you have a world where you can actually do more then talk to deal with someone trying to kill your citizens, trying to do worse.
