But despite that, Bush's presidency was generally continuous with American presidencies since World War II. He still, at root, steered the ship as though he were a believer in the narrative of America as a leader of the free world, rather than as a selfish actor who needs to get one over on everyone else in order to get ahead. Regardless of the world's judgement of Bush, I don't think it sowed much doubt in many minds about their overall relationship with America, and not just because of 9/11 or because he was just one president. The US could have continued electing Bushes forever and not much would have changed.
Whereas: Trump's presidency - especially this second term - is utterly destabilizing. He's single-handedly destroyed America's soft power and place in the world.
