The UN Security Council has been a key arbiter of international action regarding the upheavals in the Arab world in 2011. In late February, the Council issued Resolution 1970 calling for an “immediate end to the violence” in Libya, imposing sanctions and an arms embargo, and asking the International Criminal Court to investigate the regime of Col. Muammar al-Qaddafi. Less than a month later, on March 17, the Council passed Resolution 1973 authorizing NATO “to take all necessary measures” to protect Libyan civilians, leading to Qaddafi’s eventual fall from power. In late September, the Security Council will also take up the request of Palestinian leader Mahmoud ‘Abbas for full UN membership for a state of Palestine.
