But companies that enter into business deals with such governments should do their own risk management. If they find such deal unacceptable, perhaps they should have invested more into US ventures, such as the lame proposal ExxonMobil submitted to BLM for the Oil Shale pilot program.
ExxonMobil did not lose $30B as you suggested.
Risk management was I believe my initial point. To some extent profits are justified by risks, as that is where the money cames from to offset them. You must be a professional obfuscator and come across as amoral.
