Yemen was a British Colony. Years of wars and Houthis are driving force. Gaza created the storm so they decided to attack transporting ships entering the Red sea. There is a peppering effect permeating the Middle East. In Gaza, it is Hamas, in Lebanon, it is Hezbollah but now another tactic is called into effect and it affects trade (it may take an extra 10-14 days) to get shipped container loads to their detination. This time we are talking about Houthis in Yemen, one of the most impoverished countries in the world.
