Refugees as weapons

"Refugees as weapons" is a term used to describe a hostile government organizing, or threatening to organize, a sudden influx of refugees into another country or political entity with the intent of causing political disturbances in that entity. The responsible country (or sometimes a non-state actor) usually seeks to extract concessions from the targeted country and achieve some political, military, and/or economic objective.

The United States military U.S. Army Center for Army Lessons Learned released a handbook entitled "Commander's Guide to Support Operations Among Weaponized Displaced Persons, Refugees, and Evacuees". The handbook, provides a basic overview of considerations and methods of reaction should CBRN warfare be executed using dislocated civilians.

Migration coercion
Migration coercion is the utilization, or threatens to utilize, migration as an instrument to induce behavioral changes, or to gain concessions from the receiving target. In 1966, Teitelbaum and Weiner stated that in foreign policy governments create mass migrations as a tool to achieve non migrant goals.

An example during Afghanistan conflict (1978–present) is Soviet attempt to influence Pakistani decision-making by driving Afghans to seek asylum across the Durand Line.

Operation Peter Pan & Rafter crisis
Cuban exiles are fled from or left the island of Cuba after the Cuban Revolution of 1959.

Between November 1960 and October 1962, over 14,000 children were sent to the U.S. by their parents with Operation Peter Pan in response to the CIA and Cuban dissidents spreading rumors of a project by the castrist government to remove the parents' custody of their children to indoctrinate them. Authors John Scanlan and Gilburt Loescher note how the United States acceptance of Cuban emigrants after the 1959 Cuban Revolution was done in hopes they could help the United States forcibly remove the Fidel Castro government from Cuba. The acceptance of Cuban emigrants during the Freedom Flights was done in hopes of weakening the Cuban economy by draining it of workers. The United States also was generally able to paint a negative picture of Cuba by participating in the mass emigration of many who disliked Cuba and wished to flee the island. The Department of State painted Cuban emigrants in the 1960s as freedom-seeking refugees. The United States had lost its total aggressive foreign policy towards Cuba and instead viewed the island as a nuisance rather than a security threat after the Mariel boatlift. The Mariel boatlift was soon canceled after it was initiated and received little public American support. The 1994 Cuban rafter crisis was the emigration of more than 35,000 Cubans to the United States via makeshift rafts. In response to the crisis Bill Clinton would enact the Wet feet, dry feet policy where only Cuban rafters that make it to U.S. soil will be allowed to remain. The U.S. will also only approve 20,000 immigration visas a year for Cubans.

Fidel Castro benefited from the exile because he was able to remove disloyalty by directly removing disloyal citizens from Cuba, which is. Fidel Castro after sending more than 100,000 Cuban migrants (including criminals and the mentally disabled) to Florida, coerced the United States into foreign policy concessions.

Second Libyan Civil War
During the 2011 Libyan civil war, Muammar Gaddafi threatened to "flood" the European Union with migrants if it continued supporting the protesters.

Syrian Civil War
The Syrian Civil War is a multi-sided civil war in Syria fought between the Ba'athist Syrian Arab Republic led by President Bashar al-Assad, along with domestic and foreign allies, and various domestic and foreign forces opposing both the Syrian government and each other in varying combinations. NATO's four-star General in the United States Air Force commander in Europe stated on the issue of indiscriminate weapons used by Bashar al-Assad, and the non-precision use of weapons by the Russian forces - are the reason which cause refugees to be on the move.
 * "Together, Russia and the Assad regime are deliberately weaponizing migration in an attempt to overwhelm European structures and break European resolve."

Iran
In Iran, President Mahmoud Ahmadinejad expelled a number of displaced Afghans seeking refuge in Iran since 1979 to back to Afghanistan to stop United States operations (CIA).

Great Lakes refugee crisis
The Great Lakes refugee crisis the exodus of over two million Rwandans to neighboring countries of the Great Lakes region of Africa. Many of the refugees were Hutu ethnics fleeing the predominantly Tutsi Rwandan Patriotic Front (RPF), which had gained control of the country at the end of the Rwandan genocide.

Reversal of this process is the repatriation of the refugees, which is the process of returning to their place of origin or citizenship. That happened after the First Congo War, when RPF-supported rebels invaded Zaire.

South Ossetia
The Russo-Georgian War was between Georgia, Russia and the Russian-backed self-proclaimed republics of South Ossetia and Abkhazia. The war took place in August 2008 following a period of worsening relations between Russia and Georgia, both formerly constituent republics of the Soviet Union. The fighting took place in the strategically important Transcaucasia region. Humanitarian impact of the Russo-Georgian War was devastating on the civilians. In the aftermath, ethnic Georgians were expelled from South Ossetia and most of the Georgian villages were razed. Ethnic cleansing of Georgians in South Ossetia was a mass expulsion of ethnic Georgians conducted in South Ossetia and other territories occupied by Russian and South Ossetian forces. According to the 2016 census conducted by the South Ossetian authorities, 3,966 ethnic Georgians remained in the breakaway territory, constituting 7% of the region's total population of 53,532.

Russia is pushing for the international recognition of Abkhazia and South Ossetia (will be satellite states). Abkhazia and South Ossetia are disputed territories in the Caucasus. The central government of Georgia considers the republics under military occupation by Russia. They are partially recognized as independent states by Russia, Venezuela, Nicaragua, Nauru and Syria. Russia's initial recognition of the independence of Abkhazia and South Ossetia occurred in the aftermath of the Russo-Georgian War in 2008.

Indonesia

In 2015 Indonesia minister warned Australia, Indonesia could release a “human tsunami” of 10,000 asylum seekers to Australia if Canberra continues to agitate for clemency for the death row pair on Bali Nine

Turkey
In late February 2020 migrants started to gather at the Greece–Turkey border after Turkish president Recep Tayyip Erdoğan announced that he would no longer "block" refugees and migrants' "access to the border", and opened the border with Greece. Turkey's government was accused of pushing refugees into Europe for political and monetary gain.
