Trump doesn't care about anyone but himself. The only reason he ran for president again (a job he absolutely hated the first time around) was so he would stay out of jail for the myriad of crimes he committed. Now that he actually got reelected (us Americans can be incredibly dumb) he's doing everything he can to punish everyone he deems was "out to get him".

Also he adores Putin and Xi and is doing what he can to become like them. There's no conspiracy, Trump really is that much of a child.
