Vietnam War: In response to U.S. President Lyndon B. Johnson's call for "more flags" in Vietnam, Philippine President-elect Ferdinand Marcos announces he will send troops to help fight in South Vietnam.

Ferdinand Emmanuel Edralin Marcos Sr. (Tagalog: [maks], English: MAR-kawss; September 11, 1917 September 28, 1989) was a Filipino politician, lawyer, dictator, and kleptocrat who was the 10th president of the Philippines from 1965 to 1986. He ruled under martial law from 1972 until 1981 and kept most of his martial law powers until he was deposed in 1986, branding his rule as "constitutional authoritarianism":414 under his Kilusang Bagong Lipunan (New Society Movement). One of the most controversial leaders of the 20th century, Marcos's rule was infamous for its corruption, extravagance, and brutality.Marcos gained political success by claiming to have been the "most decorated war hero in the Philippines", but many of his claims have been found to be false, with United States Army documents describing his wartime claims as "fraudulent" and "absurd". After World War II, he became a lawyer then served in the Philippine House of Representatives from 1949 to 1959 and the Philippine Senate from 1959 to 1965. He was elected the President of the Philippines in 1965 and presided over an economy that grew during the beginning of his 20-year rule but would end in the loss of livelihood, extreme poverty, and a crushing debt crisis. He pursued an aggressive program of infrastructure development funded by foreign debt, making him popular during his first term, although it triggered an inflationary crisis which led to social unrest in his second term. Marcos placed the Philippines under martial law on September 23, 1972, shortly before the end of his second term. Martial law was ratified in 1973 through a fraudulent referendum. The Constitution was revised, media outlets were silenced, and violence and oppression were used against the political opposition, Muslims, suspected communists, and ordinary citizens.After being elected for a third term in the 1981 Philippine presidential election, Marcos's popularity suffered greatly, due to the economic collapse that began in early 1983 and the public outrage over the assassination of opposition leader Senator Benigno "Ninoy" Aquino Jr. later that year. This discontent, the resulting resurgence of the opposition in the 1984 Philippine parliamentary election, and the discovery of documents exposing his financial accounts and false war records led Marcos to call the snap election of 1986. Allegations of mass cheating, political turmoil, and human rights abuses led to the People Power Revolution of February 1986, which removed him from power. To avoid what could have been a military confrontation in Manila between pro- and anti-Marcos troops, Marcos was advised by US President Ronald Reagan through Senator Paul Laxalt to "cut and cut cleanly". Marcos then fled with his family to Hawaii. He was succeeded as president by Aquino's widow, Corazon "Cory" Aquino.According to source documents provided by the Presidential Commission on Good Government (PCGG), the Marcos family stole US$5 billion$10 billion from the Central Bank of the Philippines. The PCGG also maintained that the Marcos family enjoyed a decadent lifestyle, taking away billions of dollars from the Philippines between 1965 and 1986. His wife, Imelda Marcos, made infamous in her own right by the excesses that characterized her and her husband's conjugal dictatorship, is the source of the term "Imeldific". Two of their children, Imee Marcos and Ferdinand "Bongbong" Marcos Jr., are still active in Philippine politics, with Bongbong having been elected president in the 2022 election. Ferdinand and Imelda Marcos held the Guinness World Record for the largest-ever theft from a government for decades, although Guinness took the record down from their website while it underwent periodic review a few weeks before the 2022 Philippine presidential election.

Vietnam (Vietnamese: Việt Nam, [vîət nāːm] (listen)), officially the Socialist Republic of Vietnam, is a country in Southeast Asia. Located at the eastern edge of mainland Southeast Asia, it covers 311,699 square kilometres. With a population of over 96 million, it is the world's fifteenth-most populous country. Vietnam borders China to the north, Laos and Cambodia to the west, and shares maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City.Vietnam was inhabited as early as the Paleolithic age. The first known Vietnamese nation during the first millennium BC centred on the Red River Delta, located in modern-day northern Vietnam. The Han dynasty annexed and put the Vietnamese under Chinese rule from 111 BC, until the first independent dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded southward to the Mekong Delta. The Nguyễn—the last imperial dynasty—fell to French colonisation in 1887. Following the August Revolution, the nationalist Viet Minh under the leadership of communist revolutionary Ho Chi Minh proclaimed independence from France in 1945.

Vietnam went through prolonged warfare through the 20th century. After World War II, France returned to reclaim colonial power in the First Indochina War, from which Vietnam emerged victorious in 1954. The Vietnam War began shortly after, during which the nation was divided into communist North supported by the Soviet Union and China, and anti-communist South supported by the United States. Upon North Vietnamese victory in 1975, Vietnam reunified as a unitary socialist state under the Communist Party of Vietnam in 1976. An ineffective planned economy, trade embargo by the West, and wars with Cambodia and China crippled the country. In 1986, the Communist Party initiated economic and political reforms, transforming the country to a market-oriented economy.

The reforms facilitated Vietnamese integration into global economy and politics. A developing country with a lower-middle-income economy, Vietnam is one of the fastest growing economies of the 21st century. It is part of international and intergovernmental institutions including the United Nations, the ASEAN, the APEC, the CPTPP, the Non-Aligned Movement, the Organisation internationale de la Francophonie, and the World Trade Organization. It has assumed a seat on the United Nations Security Council twice. Contemporary issues in Vietnam include corruption and a poor human rights record.
