From UNIFIL Is Ineffective:
In reality, UNIFIL in Lebanon gives diplomats an excuse to do nothing about Hizbullah’s rearmament, and its presence on the ground complicates Israel’s ability to engage the terrorist army in battle. The new UNIFIL force is afraid to confront Hizbullah, unwilling to interrupt the easy flow of arms across Lebanon, and prohibited from patrolling the border with Syria. No serious observer of southern Lebanon today believes that the new, “robust” UNIFIL will prevent another round of warfare.
