Tehran’s ability to fight by, with and through third parties in foreign jurisdictions has become a valuable and effective sovereign capability that gives Iran strategic advantage in the region. Tehran has possessed a form of this capability since the Islamic Revolution in 1979, but its potency and significance have risen sharply in the past decade, to the point where it has brought Iran more regional influence and status than either its nuclear or ballistic-missile programmes. The IISS Strategic Dossier Iran’s Networks of Influence provides an understanding of how Iran builds, operates and uses this capability. Based on original field research, open-source information and interviews with a range of sources, the dossier conducts an audit of Iran’s activities in the principal regional theatres of Iraq, Lebanon, Syria and Yemen, and its reach into Bahrain, Saudi Arabia and Kuwait. It includes an examination of Tehran’s nurturing of groups such as the Houthis in Yemen, the Badr Organisation in Iraq, Hizbullah in Lebanon and Shia militias in Syria, and details related to recruitment, weapons supply, logistics and command-and-control systems. Iran’s Networks of Influence is intended through objective, fact-based analysis to inform both policymakers and practitioners, and to stimulate debate on the wider significance of Iran’s use of third-party partners and the strategic depth they afford Tehran. The dossier also examines the advantages that Iran possesses through its recent experience of conflict, and its ability to mobilise and deploy sympathetic Shia communities across theatres. In a time of rising tension in the region, the dossier looks at how Iran might further develop the use of its partnership capability and the risks and constraints it might face.

This study explores Iranian influence in Afghanistan and the implications for the United States after most U.S. forces depart Afghanistan in 2016. Iran has substantial economic, political, cultural, and religious leverage in Afghanistan. Although Iran will attempt to shape a post-2014 Afghanistan, Iran and the United States share core interests: to prevent the country from again becoming dominated by the Taliban and a safe haven for al Qaeda.

There is a saying in Arabic, me and my brother against my cousin, and me and my cousin against the outsider. Iran's Influence is the first comprehensive analysis of the role that Iran plays both in Middle Eastern and global politics. Expert Iranian author Elaheh Rostami Povey provides a much-needed account of one of the Middle East's most controversial and misunderstood countries. Based on several years of original research carried out in Iran and across the Middle East, this insightful guide presents not only a fascinating introduction to the country, but also essential new ideas to help the reader understand the Middle East.

Iran has emerged from decades of isolation and struggle to become a leading, if not the pre-eminent, regional power. Iran projects its influence throughout the Middle East and parts of Central Asia. Moreover, Iranian diplomacy is active on the world stage, with long-term projects in Africa and South America. The landmark nuclear deal of July 2015 was a major triumph and saw the Islamic Republic successfully negotiate with several world powers to reach a mutually acceptable agreement. Crucially, whilst the nuclear deal restricts Iran's nuclear programmed for at least a decade, it doesn't irreversibly dismantle any part of it. With internal Iranian politics stabilizing around a centrist administration led by President Rouhani, the country is set to continue on a path of regional strategic growth. But with clear signs that the Trump administration is determined to contain Iran's regional influence, what is the risk of a military confrontation? This book argues that Iran has developed sufficient diplomatic strength and credible military capability to deter a full-scale US military assault. But absent a dramatic lowering of tensions, there remains a risk of limited clashes, with far-reaching consequences for regional security.

In recent years, significant attention has focused upon the Islamic Republic of Iran’s nuclear ambitions, and the threat they pose to the United States and the West. Far less well understood, however, has been the phenomenon of Iran’s regional advance in America’s own Hemisphere—an intrusion that has both foreign policy and national security implications for the United States and its allies. In this collection, noted specialists and regional experts examine the various facets of Iran’s contemporary presence in Central and South America, and detail what the Islamic Republic’s growing geopolitical footprint south of the U.S. border signifies, both for Iran and for the United States.

Iran's attempts to wield its influence in Iraq have thus far yielded only mixed results, though the formation of a new government that incorporates many of Tehran's closest Iraqi allies, and the impending U.S. military withdrawal from Iraq, will present new opportunities for Iran to extend its reach. Such a move is likely to generate further Iraqi pushback, though it remains to be seen whether Iranian influence will continue to be "self-limiting" or whether this emerging reality will create new opportunites for Tehran to transform Iraq into a weak client state via a gradual process of "Lebanonization." Over the long run, the nature of the relationship between Iraq and Iran will depend largely on the security situation in Iraq, the political complexion of the Iraqi government, and the type of long-term relationship Iraq builds with its Arab neighbors and the United States. Moreover, Iraq's reemergence as a major oil exporter, likely at Iran's expense, will almost certainly heighten tensions between the two oil-exporting nations.

Since the 1979 Islamic Revolution, the strategic culture of resistance has dominated Iran’s strategic objective and foreign policy preference formation. Iran is a revisionist state that lacks overwhelming military and economic dominance in its near abroad, as such two pillars have emerged to support and export their strategic culture of resistance. These are Adaptive Resistance (pragmatism) and Designed Redundancy (deniability and insulation). These two themes of resistance provide content and structure to their strategic Influence campaigns, where “strategic Influence is the use of the elements of national power—diplomatic, military, economic, with and through information—to shape the information and operational environment in order to erode the will of the enemy…. This ‘new’ way of war is predicated on building narratives, activating identities, mobilizing proxies, and disorienting targets through the use of information in service of strategic goals.” Strategic influence is the way in which elements of the strategic culture of resistance are executed in Iran’s near abroad. To combat and defeat strategic influence campaigns, it is necessary to understand both the strategic cultural factors at play and the strategic influence campaigns that Iran deploys.
