After the central African "world war" more and more article are mentioning the risk of a similar development in the region around Syria. There have already been fights between Shiites and Sunnites in Lebanon and there is a serious risk that the Sunnite majority in Northern Lebanon joins their brethren in the adjacent Syrian Homs-Hama region to create a fundamentalist Sunni region. There are also more and more connections between the Shiites and Sunnites in Iraq and their colleagues in Syria. Jordan, with its Palestinian majority, might join the trouble too.
