These are not unrelated things. Trump and his friends are not damaging the world just for the fun of it, they're being paid for it. Follow the money (and cut off their flow).
This is one thing which the Communists have got right in theory, though they never really implemented it: "Money will never be allowed to have the last word here. It will never be allowed to be “active". It will never be permitted to become an autonomous power." (quote from "Red Plenty").
You assume there is an over arching plan of corruption, Dr Evil style.
From what I can see, Trump just hands out sinecures to random low intelligence crooks (Perry, de Vos, FFS!)
Trump, one suspects only understands hooky property deals and leaves the others to exploit other channels.
Meanwhile, every day the public obsesses about collusion/no collusion or similar the route to win debate on
whether the US should be a signature to the Paris Agreement, (for instance) gets more remote.
