Yeah we can nuke the goddamn moon with a missile controlled from earth. We have hypersonic jets that can carry nuclear payloads from bases all across the planet. Those are the first strike legs of the nuclear triad. The subs are terrible at first strike capacity, but so long as they remain hidden they can't really be prevented from assuring mutual destruction.

But also Trump didnt know the nuclear triad in 2016 and his brain was only mostly pudding back then
