Islamic Jihad Movement in Palestine in the context of "2021 Israel–Palestine crisis"

Since the Iranian Revolution in 1979, the government of the Islamic Republic of Iran has been accused by several countries of training, financing, and providing weapons and safe havens for non-state militant actors, such as Hezbollah in Lebanon, Hamas in Gaza, and other Palestinian groups such as the Islamic Jihad (IJ) and the Popular Front for the Liberation of Palestine (PFLP). These groups are designated terrorist groups by a number of countries and international bodies such as the EU, UN, and NATO, but Iran considers such groups to be "national liberation movements" with a right to self-defense against Israeli military occupation. These proxies are used by Iran across the Middle East and Europe to foment instability, expand the scope of the Islamic Revolution, and carry out terrorist attacks against Western targets in the regions. Its special operations unit, the Quds Force, is known to provide arms, training, and financial support to militias and political movements across the Middle East, including Bahrain, Iraq, Lebanon, Palestine, Syria, and Yemen.

A number of countries (Argentina, Albania, Australia, Bulgaria, Denmark, France, India, Kenya, Sweden, Thailand, United States) have accused the Iranian government and the Islamic Revolutionary Guards Corps of plotting assassinations or bombings in their countries and others against perceived enemies of Iran. In response, economic sanctions against the Iranian regime have been imposed by many countries and the United Nations. The first sanctions were imposed by the United States in November 1979, after a group of radical students seized the U.S. embassy in Tehran and took hostages. The sanctions were expanded in 1995 to include business dealings with the Iranian government. However, these sanctions have not significantly impacted the country's relationships with its proxies. The United States Department of State estimated that Iran spent more than $16 billion in support of the Assad regime and its proxies between 2012 and 2020, a period in which Iran funneled more than $700 million to Hezbollah.

The 2014 Gaza War, also known as Operation Protective Edge (Hebrew: מִבְצָע צוּק אֵיתָן, romanized: Miv'tza Tzuk Eitan, lit. 'Operation Strong Cliff'), and Battle of the Withered Grain (Arabic: معركة العصف المأكول, romanized: Maʿrakat al-ʿAṣf al-Maʾkūl), was a military operation launched by Israel on 8 July 2014 in the Gaza Strip, Palestinian territory governed by Hamas since 2007 and occupied by Israel since 1967. Following the kidnapping and murder of three Israeli teenagers in the West Bank by Hamas-affiliated Palestinian militants, the Israel Defense Forces (IDF) initiated Operation Brother's Keeper, in which it killed 10 Palestinians, injured 130 and imprisoned more than 600. Hamas reportedly did not retaliate but resumed rocket attacks on Israel more than two weeks later, following the killing of one of its militants by an Israeli airstrike on 29 June. This escalation triggered a seven-week-long conflict between the two sides, one of the deadliest outbreaks of open conflict between Israel and the Palestinians in decades. The war resulted in over two thousand deaths, the vast majority of which were Gazan Palestinian civilians. This includes a total of six Israeli civilians who were killed as a result of the conflict.

The Israeli military operation aimed to stop rocket fire into Israel from the Gaza Strip. Conversely, Hamas' attacks aimed to bring international pressure onto Israel with the strategic goal of forcing the latter to lift the naval and air blockade of the Gaza Strip; among its other goals were to end Israel's attacks on Palestinians, obtain a third party to monitor and guarantee compliance with a ceasefire, release Palestinian political prisoners and overcome its isolation. According to the BBC, Israel launched airstrikes on the Gaza Strip in retaliation to the rocket attacks by Hamas, Palestinian Islamic Jihad (PIJ), and other Palestinian militant groups.
