Foreign aid, America gives money to a country so their politicians do what America’s politicians want is standard foreign policy. If they don’t there’s the CIA and the military. None of this is new. There is intrigue and conspiracy in all of it, let’s not kid ourselves.
I would say that ending quid pro quo bribery (foreign aid) would be a good thing but it would just lead to more military intervention.
If it’s grounds for impeachment shall we impeach them all or just the guy we don’t like?
