It's not necessarily driven by anything internal. Lots of parts of the Middle East are globally significant, because of oil and gas production and the Suez canal route. That means that they attract a lot of external meddling. For example, Iran is backing the Houthis with weapons, technology, and money. The United States has done various bits of meddling too, both supportive and not. If you pour the means of conflict into a region, you will tend to get more conflict there.
