Saudi Arabia is not a ally. They are poison shilling, chem pushers that support the USA oil addiction for profit. Energy independence isn’t just a environmental issue. It’s a national security issue. Oil imports are most problematic in domestic politics and energy security when they come from countries that are openly hostile to US foreign policy and interests (Iran, Venezuela, and formerly Iraq), are former or potential future rivals (Russia) or have questionable alliances and human rights practices (Saudi Arabia). We can’t continue being beholden to these countries for our energy.
