Burma ⁱ/ˈbɜrmə/ BUR-mə, also known as Myanmar ⁱ/ˌmjɑːnˈmɑr/ MYAHN--MAR, is a country in South Asia and Southeast Asia. It is bordered by India, Bangladesh, China, Laos and Thailand. One-third of Burma's total perimeter of 1,930 kilometres (1,200 mi) forms an uninterrupted coastline along the Bay of Bengal and the Andaman Sea. At 676,578 km² (261,227 sq mi), it is the 40th largest country in the world and the second largest country in Southeast Asia. Burma is also the 24th most populous country in the world with over 60.28 million people.

Burma is home to some of the early civilizations of Southeast Asia including the Pyu and the Mon. In the 9th century, the Burmans of the Kingdom of Nanzhao, entered the upper Irrawaddy valley and, following the establishment of the Pagan Empire in the 1050s, the Burmese language and culture slowly became dominant in the country. During this period, Theravada Buddhism gradually became the predominant religion of the country. The Pagan Empire fell due to the Mongol invasions (1277–1301), and several warring states emerged. In the second half of the 16th century, the country was reunified by the Taungoo Dynasty which for a brief period was the largest empire in the history of Southeast Asia. The early 19th century Konbaung Dynasty ruled over an area that included modern Burma as well as Manipur and Assam. The country was colonized by Britain following three Anglo-Burmese Wars (1824–1885).

The President of the United States of America (acronym: POTUS) is the head of state and head of government of the United States. The president leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.

Article II of the U.S. Constitution vests the executive power of the United States in the president and charges him with the execution of federal law, alongside the responsibility of appointing federal executive, diplomatic, regulatory, and judicial officers, and concluding treaties with foreign powers, with the advice and consent of the Senate. The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. Since the founding of the United States, the power of the president and the federal government have grown substantially and each modern president, despite possessing no formal legislative powers beyond signing or vetoing congressionally passed bills, is largely responsible for dictating the legislative agenda of his party and the foreign and domestic policy of the United States. The president is frequently described as the most powerful person in the world.

Thein Sein (Burmese: သိန်းစိန် [θéɪɴ zèɪɴ]; born 20 April 1945) is a Burmese politician and former military figure who has been president of Burma (Myanmar) since March 2011. Previously, he was Prime Minister from 2007 until 2011. He is generally considered to be a moderate and reformist in the new government.

Thein Sein was born in Kyonku, British Burma (now Myanmar), a small village in what is now Ngapudaw Township in the Irrawaddy delta to parents Maung Phyo (father) and Khin Nyunt (mother). He was the youngest of three children. His parents were landless, and his father made a living carrying cargo at the river jetty and weaving bamboo mats.

Thein Sein graduated from the 9th intake of the Defense Services Academy in 1968.

Throughout Thein Sein's four-decade-long military career, he was considered a bureaucrat, not a combat soldier. In 1988, he served as a major for Sagaing Division's 55th Light Infantry Division and later served as a commander for Sagaing Division's 89th Infantry Battalion in Kalay Township. The following year, he studied at the Command and General Staff College in Kalaw, Shan State.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
