There been work in this direction for multiple decades already, but up until the confirmation that Trump won his second election, things weren't happening that quickly. Since then though, the steam train been all aboard and everyone and their mother is currently trying to reduce US dependency in pretty much every way they can.
One key distinction is the permanancy of Trumpism. The fact that existing controls in the US government cannot stop the extreme Trump actions, and in fact for many cases are explicitly supporting, gave a clear message to other governments that the risk is real, permanent and needs de-risking.
Overall Trump is a stress test on the world and found many defects that is slowly getting fixes.
