I think he was referring more to the political instability (violence) related risks of many of the oil projects. It may not effect the executives in the United States or the dollars, but it does effect the workers who have to work in those environments with political instability and violence.
Also, political situations have had them lose billions in recent years as countries like Venezuela and Russia have either out right taken over their oil platforms, wells, and other projects or made them sell their stakes in them to their own preferred groups such as state oil companies.
While the impact is nothing to their bottom line these past 3-4 years, those risks translated into real losses in many other years. Heck, the 1970s through the 1980s really sucked for them for the most part.
Now they have the political risk of the folks like Hillary Clinton saying that since they made a profit, she will reclaim it and use it to pay for alternative fuel. Can we just put a bullet in the memory of Milton Friedman now? He has only been dead a few months, so its a fresh kill.
