In case you haven't noticed, everything Trump has done since taking office, or plans to do has been about OIL - for the benefit of the OIL and GAS industry, and COAL.
Now he's over in Saudi Arabia, one of the biggest oil producers in the world, and has said things to isolate, and threaten Iran, another oil producer. He and Tillerson are also making "deals" with the Saudis. Are they deals that would bolster the OIL and GAS industries?
If tensions start to rise, and they surely could with his actions and rhetoric, that would be good for the OIL and GAS industry. It could drive the price of OIL up. If war broke out, the price of oil would skyrocket even more.
Then I think about things Trump said during the campaign. For example, if we go into a country and defeat it, we should KEEP THEIR OIL. Some believe that's why Bush-Cheney really went into Iraq, which had nationalized oil fields before the US did, and there have been stories that maps were found that divided up Iraq's oil fields to companies. Is this their ultimate goal?
