USA will not have a hostile cuba, just as Russia won’t have a hostile Ukraine, and China won’t have a hostile Taiwan on its doorstep.

USA will, from all signs, not only continue to have a hostile Cuba, but also create a hostile Mexico.

And that's even before considering the internal hostility to the regime that the deliberately-engineered major economic collapse--that is already happening despite numerous policies that will deepen it still being in the pipeline and not yet in place--will create.

The US withdrawing from international engagement, trashing alliances, and trashing its own economy may enable competing powers more space to dominate their own regions, but it doesn't do anything to strengthen the US's regional position, it radically weakens it.
