Well, the weapons are still in Cuba, thank god :) and Cuba has an air force, which I suppose was given/sold to Cuba by the USSR/China, so maybe the US can also give some F16 to Ukraine. The USSR also sent planes and soviet crews to fight the Americans in Vietnam, so there is precedent for all that.
NATO is hostile to russia’s imperial ambitions and so are all of its neighbours.
