It seems unlikely. Most of them were either lost on US soil or lost along with military personnel who died.

But the more convincing logic is: why would the US want to do that? The fewer other nations have nuclear weapons, the more power the US has over them, either because it can threaten to attack them or because it can provide nuclear weapons as a deterrent. Stationing US weapons in a foreign country and getting to set up a forward base? Heck yeah. Giving up control of those weapons and maybe having them turned against you decades down the line? Not a chance.
