I think this is overly optimistic. Countries around the world can't build strategies around the US that will only hold when the Democrats are in power. Trump and the Republican party as a whole have thrown reliability out the window. Even if the GOP come to their senses and reject the America First ideology and pop their disinformation bubble the damage has still be done to the character of state. The only option for the US is to hold on to its power by sheer muscle power, but that will only last so long.
