This is genuinely worrying. It shows contempt towards (American) democracy. Worse still is what it means - is this because of the changing nature of warfare?
AI, drones, missiles, missile-shields etc. means that unless you want to occupy a territory, you don't really need to send your army / troops to a country any more to "punish" them. If you aren't going to put boots on the ground, you don't have to worry about body bags returning home and generating (unmanageable) political anger. Thus, politicians (from superpowers) who hold a contempt for the general public may feel that there is no need any more to get the public's approval for a war as these "ungrateful" citizens aren't anyway going to volunteer for a war without a reasonable justification. The Gaza genocide has already shown that unless the victims are "white, blue-eyed blonde Christians like us" ( https://www.newslaundry.com/2022/02/28/europeans-with-blue-e... ) western politicians are genuinely not going to care about such kind of war crimes. Combine that with extremist right-wing views of a new wave of imperialism (that is all about "regime" changes and killing leaders to install puppets) all stemming from the right- in the US, a multi-polar world order doesn't just seem like a "nice idea" but a political necessity.
US is done with the UN under Trump. Will we see a rethink if/when Democrats come back and then whipsaw back when Republicans gain power again?
