I think this is a great video for this section.It explains much of the complex situation in the Middle East.Quite interesting.
How the whole area is a proxy war between Iran and Saudi.How Iraq's dictatorship under Saddam was a buffer zone between the two powers but now has descended into chaos and brings the two countries closer to war.All these Middle Eastern wars are backed by one side or the other and the interference from the West and Russia has knock on effects for the whole region.
