I wouldn’t say none whatsoever, but comparatively little. They’re already engaged in a fairly high stakes military operation costing them massive amounts of resources and manpower every year and constantly teetering on the edge of triggering a NATO involvement. Yeah they have nukes, but if they really wanted an all-out war, don’t you think they would have dropped one already?

I’d say chances are very low. First of all, the US likely has a capable early warning system and the ability to intercept a nuclear warhead in-flight, and second, the potential retaliation would likely be horrifying and not worth the risk. Worrying about armed criminal gang members who are already in the country seems to be a lot more sensible to me because they pose a more immediate threat.
