Genuinely curious why Trump is getting rid of historically the US's most reliable source for regime change. For those who don't know, the vast majority of USAID goes strictly to opposition groups in countries the US is on bad terms with, and to the ruling govrnments and millitaries of those we are on good terms with. It's how the US maintains hegemony. Some USAID went to good people and projects, of course, but never for a second think that that was its primary purpose.
One theory I saw is that the US Imperialists have noticed many of their typical regime change attempts, such as in Bolivia and Venezuela, are failing, therefore it isn't any longer an efficient use of funds. Now the US is pivoting to more open-faced aggression via tariffs and other forms of economic warfare, sanctions, and so forth. The reason, is because US hegemony is weakening, and other countries like the PRC are becoming much better alternatives to deal with.
