Since 2009, the violence and bombing by Islamic extremist group Boko Haram in Northern Nigeria has upset Nigerian government and international community a lot. The rise of Boko Haram is not new. It's the result of unsolved problems in the country's politics, economy and societies, of long-lasting North-South divide, the accumulation of ethnic/religious disputes and the influence of external factors. Spurred by the 2011 elections, Boko Haram made the year 2011 full of violence for Nigerians, and doesn't stop its crimes in the first quarter of 2012. Although Boko Harm may not disappear soon in the near future, its quick spread will be brought under control by the efforts of Nigerian government, the cooperation between Nigeria and its neighboring countries, and war on terror by the West. However, the final settlement of the issue depends on the social and economic development in the North, eradication of corruption, the boost of good governance, more jobs for the youth, and state's continuous commitment to nation-state building. <<
