See the Reagan Era, from Wikipedia:
The Reagan era or the Age of Reagan is a periodization of recent American history used by historians and political observers to emphasize that the conservative "Reagan Revolution" led by President Ronald Reagan in domestic and foreign policy had a lasting impact. It overlaps with what political scientists call the Sixth Party System. Definitions of the Reagan era universally include the 1980s, while more extensive definitions may also include the late 1970s, the 1990s, and even the 2000s. In his 2008 book, The Age of Reagan: A History, 1974–2008, historian and journalist Sean Wilentz argues that Reagan dominated this stretch of American history in the same way that Franklin D. Roosevelt and his New Deal legacy dominated the four decades that preceded it.
See Neoconservatism, from Wikipedia:
Neoconservatism is a political movement which began in the United States during the 1960s among liberal hawks who became disenchanted with the increasingly pacifist Democratic Party along with the growing New Left and counterculture of the 1960s amidst the Vietnam War. Neoconservatives typically advocate the unilateral promotion of democracy and interventionism in international relations together with a militaristic and realist philosophy of "peace through strength". They are known for espousing opposition to communism and radical politics.
Many adherents of neoconservatism became politically influential during Republican presidential administrations from the 1960s to the 2000s, peaking in influence during the presidency of George W. Bush, when they played a major role in promoting and planning the 2003 invasion of Iraq. Prominent neoconservatives in the Bush administration included Paul Wolfowitz, Elliott Abrams, Richard Perle, Paul Bremer, and Douglas Feith.
See the Dot-com Bubble, from Wikipedia:
The dot-com bubble (or dot-com boom) was a stock market bubble that ballooned during the late-1990s and peaked on Friday, March 10, 2000. This period of market growth coincided with the widespread adoption of the World Wide Web and the Internet, resulting in a dispensation of available venture capital and the rapid growth of valuations in new dot-com startups. Between 1995 and its peak in March 2000, investments in the NASDAQ composite stock market index rose by 800%, only to fall 78% from its peak by October 2002, giving up all its gains during the bubble.
During the dot-com crash, many online shopping companies, notably Pets.com, Webvan, and Boo.com, as well as several communication companies, such as Worldcom, NorthPoint Communications, and Global Crossing, failed and shut down. Others, like Lastminute.com, MP3.com and PeopleSound remained through its sale and buyers acquisition. Larger companies like Amazon and Cisco Systems lost large portions of their market capitalization, with Cisco losing 80% of its stock value.
See the Housing Bubble, from Wikipedia:
The 2000s United States housing bubble or house price boom or 2000s housing cycle was a sharp run up and subsequent collapse of house asset prices affecting over half of the U.S. states. In many regions a real estate bubble, it was the impetus for the subprime mortgage crisis. Housing prices peaked in early 2006, started to decline in 2006 and 2007, and reached new lows in 2011. On December 30, 2008, the Case–Shiller home price index reported the largest price drop in its history. The credit crisis resulting from the bursting of the housing bubble is an important cause of the Great Recession in the United States.
See the War on Terror, from Wikipedia:
The war on terror, officially the Global War on Terrorism (GWOT), is a global counterterrorist military campaign initiated by the United States following the September 11 attacks of 2001, and is the most recent global conflict spanning multiple wars. Some researchers and political scientists have argued that it replaced the Cold War.
