According to documentation the u.n. have been in Lebanon since 1978. Said to be due to border conflicts with Israel. Reportedly the force known as unifil was expanded in 2006. According to themselves, the u.n. were supposedly supporting the Lebanese government. Also said to be helping with the rebuilding of infrastructure believed to have been caused by Israeli fire. Rebuilding has been slow and remains unfinished and the Lebanese government have been criticised, perhaps due to u.n. detail and possibly because of the reported financial crisis.
Lebanon, seemingly under pressure for some time, according to recent news are being rescued by the west. Reports are that the original government have resigned. Next on the agenda according to the report is disputing the border with Israel, said to be an important area because of oil fields.
