It really shows how dangerous and impactful bad policy can be. Within two years of lifting bad regulations, America was able to become energy independent. Not being dependent on the Middle East enabled it to assert itself when needed, but also pull back from combat roles in the region. If you look at it on a macro level it becomes pretty clear why they put these policies into place. It will only be a year or two until we now have to engage in combat somewhere to secure our energy supply.
