Official website. The European Union (EU) is a politico–economic union of 28 member states that are located primarily in Europe. It has an area of 4,324,782 km2 (1,669,808 sq mi), and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency.
The EU operates through a hybrid system of supranational and intergovernmental decision-making. The seven principal decision-making bodies—known as the institutions of the European Union—are the European Council, the Council of the European Union, the European Parliament, the European Commission, the Court of Justice of the European Union, the European Central Bank, and the European Court of Auditors.
The EU traces its origins from the European Coal and Steel Community (ECSC) and the European Economic Community (EEC), formed by the Inner Six countries in 1951 and 1958, respectively. The community and its successors have grown in size by the accession of new member states and in power by the addition of policy areas to its remit. The Maastricht Treaty established the European Union in 1993 and introduced European citizenship. The latest major amendment to the constitutional basis of the EU, the Treaty of Lisbon, came into force in 2009.
Covering 7.3% of the world population, the EU in 2016 generated a nominal gross domestic product (GDP) of 16.477 trillion US dollars, constituting approximately 22.2% of global nominal GDP and 16.9% when measured in terms of purchasing power parity. Additionally, 26 out of 28 EU countries have a very high Human Development Index, according to the United Nations Development Programme. In 2012, the EU was awarded the Nobel Peace Prize. Through the Common Foreign and Security Policy, the EU has developed a role in external relations and defence. The union maintains permanent diplomatic missions throughout the world and represents itself at the United Nations, the World Trade Organization, the G8, and the G-20. Because of its global influence, the European Union has been described as a current or as a potential superpower.
Official website. The North Atlantic Treaty Organization (NATO /ˈneɪtoʊ/; French: Organisation du Traité de l’Atlantique Nord; OTAN), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. NATO’s headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO’s Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members’ defence spending is supposed to amount to 2% of GDP.
The Southeast Asia Treaty Organization (SEATO) was an international organization for collective defense in Southeast Asia created by the Southeast Asia Collective Defense Treaty, or Manila Pact, signed in September 1954 in Manila, Philippines. The formal institution of SEATO was established on 19 February 1955 at a meeting of treaty partners in Bangkok, Thailand  The organization’s headquarters were also in Bangkok. Eight members joined the organization.
Primarily created to block further communist gains in Southeast Asia, SEATO is generally considered a failure because internal conflict and dispute hindered general use of the SEATO military; however, SEATO-funded cultural and educational programs left long-standing effects in Southeast Asia. SEATO was dissolved on 30 June 1977 after many members lost interest and withdrew.
The United States still considers the mutual defense aspects of its treaty active for Australia, France, New Zealand, Philippines, Thailand, and the United Kingdom.
The Arab League (Arabic: الجامعة العربية al-Jāmiʻah al-ʻArabīyah), formally the League of Arab States (Arabic: جامعة الدول العربية Jāmiʻat ad-Duwal al-ʻArabīyah), is a regional organization of Arab countries in and around North Africa, the Horn of Africa and Arabia. It was formed in Cairo on 22 March 1945 with six members: Kingdom of Egypt, Kingdom of Iraq, Transjordan (renamed Jordan in 1949), Lebanon, Saudi Arabia, and Syria. Yemen joined as a member on 5 May 1945. Currently, the League has 22 members, but Syria‘s participation has been suspended since November 2011, as a consequence of government repression during the Syrian Civil War.
