binding, as they lack an enforcement mechanism. A minority of scholars, such as Stephen Zunes, have argued that resolutions made under Chapter VI are "still directives by the Security Council and differ only in that they do not have the same stringent enforcement options, such as the use of military force". Under Chapter VII, the council has broader power to decide what measures are to be taken in situations involving "threats to the peace, breaches of the peace, or acts of aggression." In such situations, the council is not limited to recommendations but may take action, including the use of armed force "to maintain or restore international peace and security." This was the legal basis for UN armed action in Korea in 1950 during the Korean War and the use of coalition forces in Iraq and Kuwait in 1991 and Libya in 2011. Decisions taken under Chapter VII, such as economic sanctions, are binding on UN members; the Security Council is the only UN body with authority to issue binding resolutions. The Rome Statute of the International Criminal Court recognizes that the Security Council has authority to refer cases to the Court in which the Court could not otherwise exercise jurisdiction. The Council exercised this power for the first time in March 2005, when it referred to the Court "the situation prevailing in Darfur since 1 July 2002"; since Sudan is not a party to the Rome Statute, the Court could not otherwise have exercised jurisdiction. The Security Council made its second such referral in February 2011 when it asked the ICC to investigate the Libyan government's violent response to the Libyan Civil War. Security Council Resolution 1674, adopted on 28 April 2006, "reaffirms the provisions of paragraphs 138 and 139 of the 2005 World Summit Outcome Document regarding the responsibility to protect populations from genocide, war crimes, ethnic cleansing and crimes against humanity". The Security Council reaffirmed this responsibility to protect in Resolution 1706 on 31 August of that year. These resolutions commit the Security Council to protect civilians in an armed conflict, including taking action against genocide, war crimes, ethnic cleansing and crimes against humanity. Members Permanent members The Security Council's five permanent members, below, have the power to veto any substantive resolution; this allows a permanent member to block adoption of a resolution, but not to prevent or end debate. At the UN's founding in 1945, the
