If I may go a step further in history: tearing up the JCPOA (AKA the Iran deal) was like shouting from a megaphone "the US word means nothing now". Even the Palestine situation could've been predicted 6 years before Oct 7th when the US was the very first nation to move the embassy from Tel Aviv to Jerusalem, before 5 others followed (none of them "significant").

Things have definitely accelerated in the second term, but it's not like there weren't signs that political leaders definitely noticed were disruptive, even if the wider public weren't as aware at the time.
