The company made bad decisions. I wonder how it’s going to play out now?
Chevron has the right to make business decisions, some good, some bad, as should all American companies. Most decisions made by large oil corporations are based upon long-term conditions, which in this particular case might have been to be the only one left in Venezuela doing business AFTER Maduro was removed or no longer in power. They have every right to take such a position if they think it will pay off in the long run.
What I don't agree with is the U.S. government essentially using an American company to conduct foreign policy and asking their share holders to bear the cost. We all pay taxes for that purpose and the weapons for removing someone like Maduro are readily available to a President. Use those weapons that are already paid for.
