I get the impression that the system was a little less captured and a little less refined back then. Policies weren't so extreme. Culture was very different. Most of the agencies and global organizations that exist today were formed after the war, between ~1945-65, and I feel like that was when a lot more coordination became possible to set a global agenda.
Despite Trump doing a number of things he promised, the usual policies remain unchanged, and he's also surrounded himself with a lot of questionable people.
