The theory that the US government does those wars to keep oil prices high fits the timing way better than the opposite.
I still thinks it's missing important details, but the US making wars to get more oil doesn't fit reality at all.
Venezuelan oil is more about US refineries that can only use very heavy oil, and US wells for such oil running out. Those refineries decided it is cheaper to bribe Trump than to invest into converting their factories. They are using US tax payer dolars (in a war with Venezuela) to avoid having to invest into their own conpanies.
Agreed, and it's easy to understand why the US is doing what it is doing in Latin America by reading the new national security strategy.
You're assuming they want to sell the oil in the US markets, they don't. Corporations want to sell it to other countries but they want the US to do the heavy lifting with minimal risks.
