Background | Britain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added to the original 13 as the nation expanded across the North American continent and acquired a number of overseas possessions. The two most traumatic experiences in the nation's history were the Civil War (1861-65) and the Great Depression of the 1930s. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. The economy is marked by steady growth, low unemployment and inflation, and rapid advances in technology. | Globally, the 20th century was marked by: (a) two devastating world wars; (b) the Great Depression of the 1930s; (c) the end of vast colonial empires; (d) rapid advances in science and technology, from the first airplane flight at Kitty Hawk, North Carolina (US) to the landing on the moon; (e) the Cold War between the Western alliance and the Warsaw Pact nations; (f) a sharp rise in living standards in North America, Europe, and Japan; (g) increased concerns about the environment, including loss of forests, shortages of energy and water, the decline in biological diversity, and air pollution; (h) the onset of the AIDS epidemic; and (i) the ultimate emergence of the US as the only world superpower. The planet's population continues to explode: from 1 billion in 1820, to 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1988, and 6 billion in 2000. For the 21st century, the continued exponential growth in science and technology raises both hopes (e.g., advances in medicine) and fears (e.g., development of even more lethal weapons of war). |

Maritime states have claimed limits and have so far established over 130 maritime boundaries and joint development zones to allocate ocean resources and to provide for their national security at sea. On land, ethnicity, culture, race, religion, and language have divided states into separate political entities as much as history, physical terrain, political fiat, or conquest, resulting in sometimes arbitrary and imposed boundaries. All of these factors have contributed to a wide array of boundary, borderland, and territorial disagreements that vary in intensity from unresolved or dormant to outright war. Territorial disputes may evolve from historical and/or cultural animosities, or they may be brought on by resource competition. Ethnic clashes continue to be responsible for territorial fragmentation around the world. Undemarcated, indefinite, porous, and unmanaged boundaries encourage illegal cross-border activities, uncontrolled migration, and political confrontation over boundary allocations. Other sources of contention include the use of water and mineral (especially petroleum) resources, fisheries, dams, and nuclear power plants. Many islands or island groups are also disputed, including those at sea and in streams. Nonetheless, many nations are actively cooperating to clarify, delineate, and demarcate their international borders. The tragic aspect of international discord is the impact on the sustenance and welfare of populations caught in the conflict. It is frequently left to members of the world community to cope with enormous refugee situations, and the resultant hunger, disease, and impoverishment that they create. |

Economy - overview | The US has the largest and most technologically powerful economy in the world, with a per capita GDP of $46,000. In this market-oriented economy, private individuals and business firms make most of the decisions, and the federal and state governments buy needed goods and services predominantly in the private marketplace. US business firms enjoy greater flexibility than their counterparts in Western Europe and Japan in decisions to expand capital plant, to lay off surplus workers, and to develop new products. At the same time, they face higher barriers to enter their rivals' home markets than foreign firms face entering US markets. US firms are at or near the forefront in technological advances, especially in computers and in medical, aerospace, and military equipment; their advantage has narrowed since the end of World War II. The onrush of technology largely explains the gradual development of a "two-tier labor market" in which those at the bottom lack the education and the professional/technical skills of those at the top and, more and more, fail to get comparable pay raises, health insurance coverage, and other benefits. Since 1975, practically all the gains in household income have gone to the top 20% of households. The response to the terrorist attacks of 11 September 2001 showed the remarkable resilience of the economy. The war in March-April 2003 between a US-led coalition and Iraq, and the subsequent occupation of Iraq, required major shifts in national resources to the military. The rise in GDP in 2004-07 was undergirded by substantial gains in labor productivity. Hurricane Katrina caused extensive damage in the Gulf Coast region in August 2005, but had a small impact on overall GDP growth for the year. Soaring oil prices in 2005-2007 threatened inflation and unemployment, yet the economy continued to grow through year-end 2007. Imported oil accounts for about two-thirds of US consumption. Long-term problems include inadequate investment in economic infrastructure, rapidly rising medical and pension costs of an aging population, sizable trade and budget deficits, and stagnation of family income in the lower economic groups. The merchandise trade deficit reached a record $847 billion in 2007. Together, these problems caused a marked reduction in the value and status of the dollar worldwide in 2007. | Growth in global output (gross world product, GWP) fell from 4.8% in 2000 to 2.2% in 2001 and 2.7% in 2002. The causes: sluggishness in the US economy (21% of GWP) and in the 15 EU economies (19% of GWP); continued stagnation in the Japanese economy (7.2% of GWP); and spillover effects in the less developed regions of the world. China, the second-largest economy in the world (12% of GWP), proved an exception, continuing its rapid annual growth, officially announced as 8% but estimated by many observers as perhaps two percentage points lower. Russia (2.6% of GWP), with 4% growth, continued to make uneven progress, its GDP per capita still only one-third that of the leading industrial nations. The other 14 successor nations of the USSR and the other old Warsaw Pact nations again experienced widely divergent growth rates; the three Baltic nations continued as strong performers, in the 5% range of growth. The developing nations also varied in their growth results, with many countries facing population increases that erode gains in output. Externally, the nation-state, as a bedrock economic-political institution, is steadily losing control over international flows of people, goods, funds, and technology. Internally, the central government often finds its control over resources slipping as separatist regional movements - typically based on ethnicity - gain momentum, e.g., in many of the successor states of the former Soviet Union, in the former Yugoslavia, in India, in Indonesia, and in Canada. Externally, the central government is losing decision-making powers to international bodies. In Western Europe, governments face the difficult political problem of channeling resources away from welfare programs in order to increase investment and strengthen incentives to seek employment. The addition of 80 million people each year to an already overcrowded globe is exacerbating the problems of pollution, desertification, underemployment, epidemics, and famine. Because of their own internal problems and priorities, the industrialized countries devote insufficient resources to deal effectively with the poorer areas of the world, which, at least from the economic point of view, are becoming further marginalized. The introduction of the euro as the common currency of much of Western Europe in January 1999, while paving the way for an integrated economic powerhouse, poses economic risks because of varying levels of income and cultural and political differences among the participating nations. The terrorist attacks on the US on 11 September 2001 accentuate a further growing risk to global prosperity, illustrated, for example, by the reallocation of resources away from investment to anti-terrorist programs. The opening of war in March 2003 between a US-led coalition and Iraq added new uncertainties to global economic prospects.
