Whiplash on tariffs! Why did President Trump immediately reverse himself on tariffs, first with Colombia, then with Mexico and Canada? It's because he needs their oil. Colombia exports $5.4 billion in oil to the U.S, an amount that's dwarfed by Mexico and Canada. In fact the U.S. gets 60% of its oil from Canada. The tariff postponement has little if anything to do with border 'security' and everything to do with needing those fossil fuels. Fossil fuel dependence explains the tariff drama.
