This is all about Iran.
The U.S. military has targets picked out in Syria and President Obama is trying to convince Congress that America needs to intervene. If the U.S. does go ahead with tactical strikes against the Assad regime, oil markets will be caught in the middle. Any significant reduction in exports will be felt in the rest of the world.
My own opinion is that Hadi's role will be a lot longer than a two year term, and that is exactly what Saudi Arabia, and possibly the United States, wants to see happen, because the conservative devil you know is better than the progressive devil you don't know.
With Iran possibly on the brink of acquiring nuclear capability the time for incremental measures against the custodians of those nuclear weapons is over. Canada should list the IRGC as a terrorist entity without further delay.
