I think we should all be more shocked the US kidnapped the leader of another country.
Remember the Cuban Missile Crisis?
We've frozen Venezuela out from buying or selling anything from any other country. This is how economic sanctions work. If a company or country does business with Venezuela, we block them from doing business in the USA.
What else is Venezuela supposed to do? Of course they're going to sell oil to countries that we don't like. It's the first thing that happens when we place severe economic sanctions on another country.
