Can't you see there is no special problem? Even after a military conflict, you've to either actually go into that country and start an intensive political reconstruction (e.g., Germany & WWII – which is not an option here, because of the nuclear scenario) or you have to deal with the problem of resurgent conflicts (in the past 70 years or so, they always did pop again).

You were contesting the need for a political solution. So, where is your special, proven way? On the other hand, if there's need for a political resolution, why have the military interlude, at all?

If you are ignoring the conflict, assuming, there's just a bad actor and everyone else is just in the right, you're actually part of the problem and the resurgence will be nearly guaranteed. As can be observed in all those amazingly long-lived zones of conflict, where only instability is stable, we've established after WWII and we're constantly adding to. It simply doesn't work.
