Interesting -- but no mention made of recent additional US Navy units, including another aircraft carrier, being sent into the area.
The other unmentioned piece of this puzzle is also worrysome: what if Iran and Venezuela act in concert to limit the supply of oil entering the world market?
The USA would be fine since we can cut consumption 50% immediately and another 25% in a month and don't really need to import. The other oil burning countries would have a big problem since they are already as green as they can get and have to import.
