UN Security Council Resolution 1559 and US multilateralism

United Nations security council resolution 1559 was adopted by the security council on September 2, 2004 by a vote of 9 in favor (Angola, Benin, Chile, France, Germany, Romania, Spain, United Kingdom, United States), to none against, with 6 abstentions (Algeria, Brazil, China, Pakistan, Philippines, Russian Federation).
The resolution addresses two main issues that had been worrying the international community for months. One of them is the disbanding and disarmament of all Lebanese and non-Lebanese militias, a diplomatic way to target directly Syria and Iran, two countries which are the main backers of the Lebanese "Resistance" movement Hizbullah. Also, Syria had more than 35.000 troops stationed in Lebanon, in violation of several resolutions.
