Since the 1800s, the United States has sought to advance its interests in what currently exists as the Lebanese Republic. This assessment will look at the shape that policy has taken since the 2006 Israel-Hezbollah war in the context of historical relations. After doing so, three questions will be addressed: What have been the policies of Iran and Syria toward Lebanon during this time period, how effective has U.S. policy been since 2006 in undermining Iranian and Syrian influence and what policies should the United States adopt to offset future destabilizing influence from these countries. It is concluded that the current policy suffers from substantial contradictions and shortcomings in addressing the Syrian and Iranian threats, particularly regarding Hezbollah. A new policy in the form of enhanced military and developmental support is advocated, as are steps to encourage rapprochement between Lebanon and its neighbors.
