The Islamic Revolutionary Guard Corps, also known as the Iranian Revolutionary Guards, is a multi-service primary branch of the Iranian Armed Forces. It was officially established by Ruhollah Khomeini as a military branch in May 1979 in the aftermath of the Iranian Revolution. Whereas the Iranian Army protects the country's sovereignty in a traditional capacity, the IRGC's constitutional mandate is to ensure the integrity of the Islamic Republic. Most interpretations of this mandate assert that it entrusts the IRGC with preventing foreign interference in Iran, thwarting coups by the traditional military, and crushing "deviant movements" that harm the ideological legacy of the Islamic Revolution. Currently, the IRGC is designated as a terrorist organization by Bahrain, Canada, Saudi Arabia, Sweden and the United States.
The Quds Force is one of five branches of Iran's Islamic Revolutionary Guard Corps (IRGC) specializing in unconventional warfare and military intelligence operations. U.S. Army's Iraq War General Stanley McChrystal describes the Quds Force as an organization analogous to a combination of the CIA and the Joint Special Operations Command (JSOC) in the United States. Responsible for extraterritorial operations, the Quds Force supports non-state actors in many countries, including Hezbollah, Hamas, Palestinian Islamic Jihad, the Houthi movement, and Shia militias in Iraq, Syria, and Afghanistan. According to Michael Wigginton et al., the Al-Quds Force is "a classic example of state-sponsored terrorism."
Since the Iranian Revolution in 1979, the Islamic Republic of Iran has been embroiled in tense relations with the U.S. and its allies. Following the hostage crisis, both countries severed relations. Since then, both countries have been involved in numerous direct confrontations, diplomatic incidents, and proxy wars throughout the Middle East, which has caused the tense nature of the relationship between the two to be called an 'international crisis'. Both countries have often accused each other of breaking international law on several occasions. The U.S. has often accused Iran of sponsoring terrorism and of illegally maintaining a nuclear program, as well as using strong rhetoric against Israel, of which Iran has questioned its legitimacy and its right to exist while supporting Hamas, an antizionist terrorist group in the Gaza Strip. Meanwhile, Iran has often accused the U.S. of human rights violations and of meddling in their affairs, especially within the Iranian Democracy Movement.
The war on terror, officially the Global War on Terrorism (GWOT), is a global military campaign initiated by the United States following the September 11 attacks of 2001, and is the most recent global conflict spanning multiple wars. Some researchers and political scientists have argued that it replaced the Cold War.
The Houthi movement, officially known as Ansar Allah, is a Shia Islamist political and military organization that emerged from Yemen in the 1990s. It is predominantly made up of Zaidi Shias, with their namesake leadership being drawn largely from the Houthi tribe.
The Axis of Resistance is an informal Iranian-led political and military coalition in the Middle East.
Many states began to intervene against the Islamic State, in both the Syrian civil war and the War in Iraq (2013–2017), in response to its rapid territorial gains from its 2014 Northern Iraq offensives, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian Civil War. These efforts are called the war against the Islamic State (ISIS), or the International military intervention against Islamic State (ISIS). In later years, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. All these efforts significantly degraded the Islamic State's capabilities by around 2019–2020. While moderate fighting continues in Syria, as of 2024, ISIS has been contained to a manageably small area and force capability.
The Military force of the Islamic State is the fighting force of the Islamic State (IS). The total force size at its peak was estimated from tens of thousands to over two hundred thousand. IS's armed forces grew quickly during its territorial expansion in 2014. The IS military, including groups incorporated into it in 2014, openly operates and controls territory in multiple cities in Libya and Nigeria. In October 2016, it conquered the city of Qandala in Puntland, Somalia. It conquered much of eastern Syria and western Iraq in 2014, territory it lost finally only in 2019. It also has had border clashes with and made incursions into Lebanon, Iran, and Jordan. IS-linked groups operate in Algeria, Pakistan, the Philippines, and in West Africa. In January 2015, IS was also confirmed to have a military presence in Afghanistan and in Yemen.
The Yemeni civil war is an ongoing multilateral civil war that began in late 2014 mainly between the Rashad al-Alimi-led Presidential Leadership Council and the Mahdi al-Mashat-led Supreme Political Council, along with their supporters and allies. Both claim to constitute the official government of Yemen.
On 26 March 2015, Saudi Arabia, leading a coalition of nine countries from West Asia and North Africa, launched a military intervention in Yemen at the request of Yemeni president Abdrabbuh Mansur Hadi, who had been ousted from the capital, Sanaa, in September 2014 by Houthi insurgents during the Yemeni Civil War. Efforts by the United Nations to facilitate a power sharing arrangement under a new transitional government collapsed, leading to escalating conflict between government forces, Houthi rebels, and other armed groups, which culminated in Hadi fleeing to Saudi Arabia shortly before it began military operations in the country.
Iran and Saudi Arabia are engaged in an ongoing struggle for influence in the Middle East and other regions of the Muslim world. The two countries have provided varying degrees of support to opposing sides in nearby conflicts, including the civil wars in Syria and Yemen; and disputes in Bahrain, Lebanon, Qatar, and Iraq. The struggle also extends to disputes or broader competition in other countries globally including in West, North and East Africa, South, Central, Southeast Asia, the Balkans, and the Caucasus.
The Islamic State – Yemen Province is a branch of the militant Islamist group Islamic State (IS), active in Yemen. IS announced the group's formation on 13 November 2014.
The Followers of Zainab Brigade, also known as the Zainebiyoun Brigade or Zainebiyoun Division, is a Pakistani Shia Khomeinist militant group actively engaged in the Syrian Civil War. It draws recruits mainly from Shia Pakistanis living in Iran, with some also Shia Muslim communities living in various regions of Pakistan.
The origins of the Islamic State group can be traced back to three main organizations. Earliest of these was the "Jamāʻat al-Tawḥīd wa-al-Jihād" organization, founded by the Jihadist leader Abu Mus'ab al-Zarqawi in Jordan in 1999. The other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces. These included the "Jaish al-Ta'ifa al-Mansurah" group founded by Abu Omar al-Baghdadi in 2004 and the "Jaysh Ahl al-Sunnah wa’l-Jama’ah" group founded by Abu Bakr al-Baghdadi and his associates in the same year.
