The US has used its power to promote democracy, human rights and international law  The collapse of the Soviet Union and the victory of liberal democracy over communism have provided the US with more impetus to actively promote democracy, human rights and international norms and law. Under President Clinton, the Leahy Amendment to the Defense Appropriations Act of 1998 and the Religious Persecution Act of the same year demonstrated this change in priorities. Democracy promotion also became a core element of George W. Bush’s National Security Strategy of 2002, and has been a key motivating factor in President Obama’s response to the Arab Spring, where the US has supported democratic forces against dictators such as Hosni Mubarak of Egypt and Colonel Gaddafi of Libya. The US under Obama has also provided leadership in the UN Human Rights Council[12], and holds governments to account through The Bureau of Democracy, Human Rights and Labour (DRL), which also forges and maintains global partnerships to promote human rights and democracy.[13]  [12] Brookings, ‘U.S. Leadership at the U.N.
