Ocean safety

One of the reasons that globalization was possible is because since the end of WW 2 the US Navy guaranteed the safety of the oceans and therefor all countries could trade free without fear of high jacking. The US moved away from destroyer based Navy to a carrier base and can no longer protect the shipping lanes. Big news. Yesterday the Iranians seized a Turkish oil tanker with 800,000 barrels of crude. If this thing starts to happen China will be in big trouble because all of their oil comes from far away by ship.
