The USA is currently run by oligarchs. They try to buy their way
into other countries via corruption. How much kickback did the
government of Albania get already? It is highly suspicious how
supportive they are of Trump.
Incompetent oligarchs. If you can't even successfully bribe the Albanian or Serbian government, you are just really bad at corruption. Those are (sadly) among the most corrupt countries in the world.
edit: the governments appear to be supportive, but obviously aren't as supportive as they could be. Probably taking the bribe and not doing as much as they could.
Which backfired after Trump won twice in US. But it's just business.
