I agree the world order is changing, however for the last number of years even longer there has been a widespread push for the States to stop meddling in the world. Certainly the last years of the Obama years saw just such a retreat.. Obviously there is much to dislike about Trump, but the "hawks" are re-emerging in the States and if challenged Trump will defer to the hawks. Trump's base may wish to a certain degree for the States to pull inward, but there is that mentality that the States can not be seen to shoved aside. There is a certain reverse psychology at play here, where if the States is written off as being weak and countries lack confidence in it, then the States will revert to assuming its prominent place as the world's policeman.
