>does feel its back to might is right, and the last 80 years of relative peaceful times is sunsetting.

Depending on your perspective, 'might is right' never changed. The US has forced its policies on other nations through quiet force for a long time. I think the only thing that's changed is that Trump wants to say the quiet part out loud now which makes it way easier to push back on. Combine that with the fact that Trump has 0 political ambitions outside of just being in power and it becomes very easy to just ignore what you hear coming from the top. Often it clearly has no thought put behind it, seems vindictive in nature, and is forgotten the next day, like a child's tantrum. To circle back a little, now that the US in such a passive state due to this, a lot of other countries feel safer to push their influence on the world because they see no repercussions for what others are doing.
