John F. Kennedy in the context of "Richard Nixon"

In government and politics, inauguration is the process of swearing a person into office and thus making that person the incumbent. Such an inauguration commonly occurs through a formal ceremony or special event, which may also include an inaugural address by the new official.

The word inauguration stems from the Latin augur, which refers to the rituals of ancient Roman priests seeking to interpret if it was the will of the gods for a public official to be deemed worthy to assume office.

The length of a full four-year term of office for a president of the United States usually amounts to 1,461 days (three common years of 365 days plus one leap year of 366 days). The listed number of days is calculated as the difference between dates, which counts the number of calendar days except the first day (day zero). If the first day were included, all numbers would be one day more, except Grover Cleveland would have two more days, as he served two full nonconsecutive terms.

Of the individuals elected president, four died of natural causes while in office (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned from office (Richard Nixon).

Breaking news, also called late-breaking news, a special report, special coverage, or a news flash, is a current issue that warrants the interruption of a scheduled broadcast in order to report its details. News broadcasters also use the term for continuing coverage of events of broad interest to viewers, attracting accusations of sensationalism.

The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. Apollo was conceived during Project Mercury and executed after Project Gemini. It was conceived in 1960 as a three-person spacecraft during the presidency of Dwight D. Eisenhower. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to the U.S. Congress on May 25, 1961.

Kennedy's goal was accomplished on the Apollo 11 mission, when astronauts Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module (LM) on July 20, 1969, and walked on the lunar surface, while Michael Collins remained in lunar orbit in the command and service module (CSM), and all three landed safely on Earth in the Pacific Ocean on July 24. Five subsequent Apollo missions also landed astronauts on the Moon, the last, Apollo 17, in December 1972. In these six spaceflights, twelve people walked on the Moon.

A given name (also known as a forename or first name) is the part of a personal name that identifies a person, potentially with a middle name as well, and differentiates that person from the other members of a group (typically a family or clan) who have a common surname. The term given name refers to a name usually bestowed at or close to the time of birth, usually by the parents of the newborn. A Christian name is the first name which is given at baptism, in Christian custom.

In informal situations, given names are often used in a familiar and friendly manner. In more formal situations, a person's surname is more commonly used. In Western culture, the idioms "on a first-name basis" and "being on first-name terms" refer to the familiarity inherent in addressing someone by their given name.

In many societies, a surname, last family name, or first family name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several given names and surnames are possible in the full name. In modern times most surnames are hereditary, although in most countries a person has a right to change their name.

Depending on culture, the surname may be placed either at the start of a person's name, or at the end. The number of surnames given to an individual also varies: in most cases it is just one, but in Portuguese-speaking countries and many Spanish-speaking countries, two surnames (one inherited from the mother and another from the father) are used for legal purposes. Depending on culture, not all members of a family unit are required to have identical surnames. In some countries, surnames are modified depending on gender and family membership status of a person. Compound surnames can be composed of separate names.

The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian and Cambodian Civil Wars, which ended with all three countries becoming communist in 1975.

After the defeat of the French Union in the First Indochina War that began in 1946, Vietnam gained independence in the 1954 Geneva Conference but was divided in two at the 17th parallel: the Viet Minh, led by Ho Chi Minh, took control of North Vietnam, while the US assumed financial and military support for South Vietnam, led by Ngo Dinh Diem. The North Vietnamese supplied and directed the Viet Cong (VC), a common front of dissidents in the south which intensified a guerrilla war from 1957. In 1958, North Vietnam invaded Laos, establishing the Ho Chi Minh trail to supply the VC. By 1963, the north had covertly sent 40,000 soldiers of its People's Army of Vietnam (PAVN), armed with Soviet and Chinese weapons, to fight in the insurgency in the south. President John F. Kennedy increased US involvement from 900 military advisors in 1960 to 16,000 in 1963 and sent more aid to the Army of the Republic of Vietnam (ARVN), which failed to produce results. In 1963, Diem was killed in a US-backed military coup, which added to the south's instability.

The Immigration and Nationality Act of 1965, also known as the Hart–Celler Act and more recently as the 1965 Immigration Act, was a federal law passed by the 89th United States Congress and signed into law by President Lyndon B. Johnson. The law abolished the National Origins Formula, which had been the basis of U.S. immigration policy since the 1920s. The act formally removed de facto discrimination against Southern and Eastern Europeans as well as Asians, in addition to other non-Western and Northern European ethnicities from the immigration policy of the United States.

The National Origins Formula had been established in the 1920s to preserve American homogeneity by promoting immigration from Western and Northern Europe. During the 1960s, at the height of the civil rights movement, this approach increasingly came under attack for being racially discriminatory. The bill is based on the draft bill sent to the Congress by President John F. Kennedy, who opposed the immigration formulas, in 1963, and was introduced by Senator Philip Hart and Congressman Emanuel Celler. However, its passage was stalled due to opposition from conservative Congressmen.
