A report, published on US Foreign Affairs Website, analyses the crisis in Libya after the threat of Daesh. Indeed, Libya remains divided between the Government of National Accord (GNA) and the opposition costituted around General Jhalifa Haftar, Head of the army of the House of Representative. USA sees in this instability a possibility to drive the leading forces, and keep the leadership in Libya (in concurrence with Russia, and United Arab Emirates (UAE)).One of the most important risk of instability comes from the national concurrence. Haftar told that he will control Tripoli soon. Finally the rapport conclude that, it looks impossible to reach Libyan’s unity by force, only a political solution could. Trump administration need to push in this way, if it wants reach Lybian’s unity.
