Lebanon and Israel don’t talk to each other directly, so UNIFIL acts as a mediator. UNIFIL’s Liaison Branch is part of this mechanism. With the conflicting parties – Lebanon and Israel – still technically in a state of war, when tensions are high any violation of the Blue Line, any inadvertent movement in the area, or any imprudent remark may cause an eruption of violence. Only an enduring UNIFIL presence all along the Blue Line can ensure that the smallest incident will not escalate into a greater crisis.
