Trump is merely another step in the bar being lowered. And make no mistake, it can go lower.
The Western acceptance of authoritarianism in exchange for a good deal is what got us here. It's not just the US; it's Europe too. Putin did what he did because he knew that Europe was willing to exchange the end of Russian subordination to the post-Cold War world order for cheap gas. Middle Eastern countries have seen their awful human rights records punished by the granting of a World Cup by FIFA and European tourism to Dubai. Both China and Russia were made Olympic hosts in the last 20 years. Russia hosted a World Cup in 2018, four years after the invasion of Crimea and ten years after its invasion of Georgia.
The message? Authoritarianism pays.
