This report summarizes the eight cases initiated by Members of Congress in which final rulings were reached, which concerned U.S. military activities in El Salvador, Nicaragua, and Grenada; military action taken during the Persian Gulf conflict between Iraq and Iran; U.S. activities in response to Iraq's invasion of Kuwait (prior to the congressional authorization); U.S. participation in NATO's action in Kosovo and Yugoslavia; and U.S. military action in Libya.

This report focuses on the United States' relationship with Iran and how the Obama Administration is handling prior administration's economic sanctions against Iran. The Obama Administration's policy approach toward Iran has contrasted with the Bush Administration's by attempting to couple the imposition of sanctions to an active and direct U.S. effort to negotiate with Iran on the nuclear issue. That approach was not initially altered because of the Iranian dispute over its June 12, 2009, elections. However, with subsequent negotiations yielding no firm Iranian agreement to compromise, since early 2010 the Administration has focused on achieving the imposition of additional U.N., U.S., and allied country sanctions whose cumulative effect would be to compel it to accept a nuclear bargain.

This report discusses the situation immediately following the completion of the U.S. withdrawal from Iraq on December 18, 2011, when relations among major political factions worsened substantially, threatening Iraq's stability and the legacy of the U.S. intervention in Iraq. It includes an overview of historical and current political, military, and governance issues as well as an analysis of Iraq in relation to the other nations in the region.
