"United States support for non-state terrorists has been prominent in Latin America, the Middle East, and Southern Africa. From 1981 to 1991, the United States provided weapons, training, and extensive financial and logistical support to the Contra rebels in Nicaragua, who used terror tactics in their fight against the Nicaraguan government. At various points the United States also provided training, arms, and funds to terrorists among Cuban exiles, such as Orlando Bosch and Luis Posada Carriles.
Various reasons have been given to justify this support. These include destabilizing political movements that might have aligned with the Soviet Union during the Cold War, including popular democratic and socialist movements. Such support has also formed a part of the war on drugs. Support was often geared toward ensuring a conducive environment for American corporate interests abroad, especially when these interests came under threat from democratic governments."
"In 1984 the Nicaraguan government filed a suit in the International Court of Justice (ICJ) against the United States. Nicaragua stated that the contras were completely created and managed by the U.S.Although this claim was rejected, the court found overwhelming and undeniable evidence of a very close relationship between the Contras and the United States.The U.S. was found to have had a very large role in providing financial support, training, weapons, and other logistical support to the Contras over a lengthy period of time, and that this support was essential to the Contras.
In 1984, the ICJ ordered the United States to stop mining Nicaraguan harbors, and respect Nicaraguan sovereignty. A few months later the court ruled that it did have jurisdiction in the case, contrary to what the U.S. had argued. The ICJ found that the U.S. had encouraged violations of international humanitarian law by assisting paramilitary actions in Nicaragua. The court also criticized the production of a manual on psychological warfare by the U.S. and its dissemination of the Contras. The manual, amongst other things, provided advice on rationalizing the killing of civilians, and on targeted murder. The manual also included an explicit description of the use of "implicit terror."
Having initially argued that the ICJ lacked jurisdiction in the case, the United States withdrew from the proceedings in 1985. The court eventually ruled in favor of Nicaragua, and judged that the United States was required to pay reparations for its violation of International law. The U.S. used its veto on the United Nations Security Council to block the enforcement of the ICJ judgement, and thereby prevented Nicaragua from obtaining any compensation."
"The United States government provided support to several Cuban exiles after the Cuban Revolution in 1959, especially under the administration of George H. W. Bush. Among the most prominent of these were Orlando Bosch and Luis Posada Carriles, who were implicated in the 1976 bombing of a Cuban plane. Bosch was also held to be responsible for 30 other terrorist acts, while Carriles was a former CIA agent convicted of numerous terrorist acts committed while he was linked to the agency. Other Cuban exiles involved in terrorist acts, Jose Dionisio Suarez and Virgilio Paz Romero, two other Cuban exiles who assassinated the Chilean diplomat Orlando Letelier in Washington in 1976, were also released by the administration of George H.W. Bush."
"The FR Yugoslav authorities regarded the ethnic Albanian Kosovo Liberation Army (KLA) as a terrorist groupthough many European governments did not. In February 1998, U.S. President Bill Clinton's special envoy to the Balkans, Robert Gelbard, condemned both the actions of the Yugoslav government and of the KLA, and described the KLA as "without any questions, a terrorist group". UN resolution 1160 took a similar stance. At first, NATO had stressed that KLA was "the main initiator of the violence" and that it had "launched what appears to be a deliberate campaign of provocation".
The United States (and NATO) directly supported the KLA. The CIA funded, trained and supplied the KLA (as they had earlier trained and supplied the Bosnian Army).As disclosed to The Sunday Times by CIA sources, "American intelligence agents have admitted they helped to train the Kosovo Liberation Army before NATO's bombing of Yugoslavia".In 1999, a retired colonel said that KLA forces had been trained in Albania by former US military working for MPR"
"The United States has provided extensive lethal and non-lethal aid to many Syrian militant groups fighting against the Syrian government, an ally of Russia, during the Syrian civil war.Through operation Timber Sycamore, several billions dollars worth of weaponry were delivered to a wide array of Syrian Jihadist groups, many of which often fought alongside al-Qaeda's al-Nusra Front and ISIS. The Syrian government has directly accused the United States of sponsoring terrorism in Syria, despite videos of rebel fighters engaging in cannibalism and public executions circulating online.The United States government was also criticized by Iran for its silence following the beheading of a child by the Islamist group Nour al-Din al-Zenki, a group that is a recipient of US military aid and is accused of many war crimes by Amnesty International.
an investigation by journalists Phil Sands and Suha Maayeh revealed that rebels supplied with weapons from the Military Operations Command in Amman sold a portion of them to local arms dealers, often to raise cash to pay additional fighters. Some MOC-supplied weapons were sold to Bedouin traders referred to locally as "The Birds" in Lajat, a volcanic plateau northeast of Daraa, Syria. According to rebel forces, the Bedouins would then trade the weapons to ISIL, who would place orders using the encrypted WhatsApp messaging service. Two rebel commanders and a United Kingdom weapons monitoring organization maintain that MOC–supplied weapons have made their way to ISIL forces.
Another study conducted by private company Conflict Armament Research at the behest of the European Union and Deutsche Gesellschaft für Internationale Zusammenarbeit found that external support for anti-Assad Syrian rebels "significantly augmented the quantity and quality of weapons available to [ISIL] forces,"including, in the most rapid case diversion they documented, "anti-tank weapons purchased by the United States that ended up in possession of the Islamic State within two months of leaving the factory.""
