"The uprising against Bahrain's Al Khalifa ruling family that began on February 14, 2011, has diminished in intensity, but continued incarceration of dissident leaders, opposition boycotts of elections, and small demonstrations counter government assertions that Bahrain has 'returned to normal.' The mostly Shiite opposition has not achieved its goal of establishing a constitutional monarchy, but the unrest has compelled the ruling family to undertake some modest reforms. Reflecting some radicalization of the opposition, underground factions have claimed responsibility for bombings and other attacks primarily against security officials. [...] Bahrain has fewer financial resources than do most of the other GCC [Gulf Cooperation Council] states and has always had difficulty improving the living standards of the Shiite majority. The unrest has, in turn, further strained Bahrain's economy by driving away potential foreign investment in Bahrain-an effect compounded by the fall in oil prices since mid-2014."
