The Yemen conflict

"The conflict has become self-perpetuating, giving rise to a war economy as tribes, army officers and state officials have seized the opportunity to control the porous border with Saudi Arabia and the Red Sea coastline. Tribal leaders and senior officials have amassed military hardware and profit from illegal sales of army stockpiles. Continued operations have justified increased military budgets without government or independent oversight. As competition over resources intensified, the benefits of war exceeded its drawbacks – at least for the elites involved." (thanks Rayman)
