We could just bomb them, not nuke them, but bombing runs. We can engage them without having to invade on foot.
Of course, idk why there's any talk of nukes
you think conventionals will be able to bomb out a heavily forested country with a fanatical government?
didn't work in ww2, didn't work in nam, didn't work in afghan, won't work in korea. we'd initially score good hits- established, visible forts and whatnot- but the moment they mobilize into the trees, you'd have to napalm entire swaths of land to have any meaningful impact- and i really do mean swaths. remember- bombing didn't work in nam, and considering CIA, al-qaeda and the taliban are all still around... it's not working on them, either. germany didn't surrender when entire cities had been wiped by firebombs- the allies invaded them with boots on the ground. ...but japan did surrender when they were nuked.
conventional bombing is a tool to aid other means of warfare, not a dedicated fighting strategy in its own right. bombs can demoralize the civilian world and wreak havoc on enemy industrial capacity, but even cavedwelling terrorists can get mosins and AKs like we americans get popcorn. we bombed the hell out of omaha beach, yet it was still the bloodiest beachhead the allies ever took. bombs have never have been a standalone option and they never will be.
the nuclear option, a CIA-backed coup (which would be incredibly hard to pull off and even bloodier than an invasion when it inevitably causes a civil war), and a full scale invasion are our only absolutist options.
otherwise, we stick to peaceful methods. i defer to what seventh has said on that side of things. if you insist on war, go back and read my prior post. we cannot half-ass a war against a nuclear state.
