The Commander of the US Air Forces Central Command for Southwest Asia says he’s impressed with the work of the Saudi-led, Arab coalition in Yemen. Speaking at a press conference at the Dubai Airshow, Lieutenant General Charles Q. Brown Jr said both the Arab coalition and the United States were ‘of the same mind set.’ Meanwhile, US Air Force Secretary, Deborah Lee James, spoke of the progress made by the US-led coalition against IS in Iraq and Syria. She said that it would take years to defeat the group, but the coalition has already pushed them back, striking key command centres, equipment areas, as well as their sources of revenue.
