Middle East Balance of Power Matures

George Friedman writes: Last week, a coalition of predominantly Sunni Arab countries, primarily from the Arabian Peninsula and organized by Saudi Arabia, launched airstrikes in Yemen that have continued into this week. The airstrikes target Yemeni al-Houthis, a Shiite sect supported by Iran, and their Sunni partners, which include the majority of military forces loyal to former President Ali Abdullah Saleh. What made the strikes particularly interesting was what was lacking: U.S. aircraft. Although the United States provided intelligence and other support, it was a coalition of Arab states that launched the extended air campaign against the al-Houthis.
