The United States recognized the independence of Armenia, Azerbaijan, and Georgia when the former Soviet Union broke up at the end of 1991. The United States has fostered these states' ties with the West in part to end their dependence on Russia for trade, security, and other relations. The United States has pursued close ties with Armenia to encourage its democratization and because of concerns by Armenian Americans and others over its fate. Close ties with Georgia have evolved from U.S. contacts with its pro-Western leadership. Successive Administrations have supported U.S. private investment in Azerbaijan's energy sector as a means of increasing the diversity of world energy suppliers. The United States has been active in diplomatic efforts to resolve regional conflicts in the region. As part of U.S. global counter-terrorism efforts, the U.S. military in 2002 began providing equipment and training for Georgia's military and security forces. Troops from all three regional states have participated in stabilization efforts in Afghanistan and Iraq. The regional states also have granted transit privileges for U.S. military personnel and equipment bound to and from Afghanistan. Beginning on August 7, 2008, Russia and Georgia warred over Georgia's breakaway regions of Abkhazia and South Ossetia. Russian troops quickly swept into Georgia, destroyed infrastructure, and tightened their de facto control over the breakaway regions before a ceasefire was concluded on August 15. The conflict has had long-term effects on security dynamics in the region and beyond. Russia recognized the independence of Abkhazia and South Ossetia, but the United States and nearly all other nations have refused to follow suit. Russia established military bases in Abkhazia and South Ossetia-in violation of the ceasefire accords-that buttress its long-time security presence in Armenia. Although there were some concerns that the South Caucasus had become less stable as a source and transit area for oil and gas, Kazakhstan and Turkmenistan are barging oil across the Caspian Sea for transit westward. Also, the United States and the European Union still support building more east-west pipelines through Turkey to bring Azerbaijani and perhaps other gas to European markets. Issues of concern in the 113th Congress regarding the South Caucasus may include Armenia's independence and economic development; Azerbaijan's energy development; and Georgia's recovery from Russia's August 2008 military incursion. At the same time, concerns have been raised about the status of human rights and democratization in the countries; the ongoing Armenia-Azerbaijan conflict over the breakaway Nagorno Karabakh region; and ongoing threats posed to Georgia and the international order by Russia's 2008 incursion and its diplomatic recognition of South Ossetia and Abkhazia. Congress has continued to oversee the region's role as part of the Northern Distribution Network for the transit of U.S. and NATO military supplies to and from Afghanistan. Georgia's aspirations for NATO membership have received ongoing congressional support. Many Members of Congress have evinced interest in recent political trends in Georgia following the peaceful transfer of party control in the October 2012 legislative election and in the wake of an October 2013 presidential election. Some Members of Congress and other policy makers believe that the United States should provide greater support for the region's increasing role as an east-west trade and security corridor linking the Black Sea and Caspian Sea regions, and for Armenia's inclusion in such links. They urge greater U.S. aid and conflict resolution efforts to contain warfare, crime, smuggling, and terrorism, and to bolster the independence of the states. Others urge caution in adopting policies that will increase U.S. involvement in a region beset by ethnic and civil conflicts.
