Iran does not pose a conventional military threat of mass invasion to its Arab neighbors. Instead, it exerts influence through a sophisticated strategy of proxy warfare, ideological expansion, nuclear brinkmanship, and control over critical energy chokepoints. This asymmetric approach has left Arab governments—from the Gulf monarchies to states in the Levant—deeply wary of Tehran’s intentions and capabilities.
At the heart of Arab concerns is Iran’s “Axis of Resistance,” a network of allied militias and political movements stretching across the region. This includes Hezbollah in Lebanon, the Houthis in Yemen, various Shia armed groups in Iraq and Syria, and ties to Palestinian factions such as Hamas and Islamic Jihad. These proxies allow Iran to project power, destabilize rivals, and create leverage without committing its own regular forces to direct combat. For Gulf states, the threat is tangible: cheap drones and missiles launched by proxies can target oil facilities, airports, and cities, while Iran maintains plausible deniability. The prolonged conflict in Yemen, Red Sea shipping disruptions, and Iran’s role in sustaining the Assad regime in Syria have demonstrated how effectively this model ties down adversaries and shifts regional power balances.
Compounding the security challenge is a deep sectarian and ideological rivalry. Since the 1979 Islamic Revolution, Iran has positioned itself as a revolutionary Shia power challenging the legitimacy of Sunni Arab monarchies and Western alliances. Saudi Arabia, in particular, views itself as the custodian of Sunni Islam and traditional Arab leadership. This Sunni-Shia divide, while often geopolitical rather than purely theological, fuels mutual suspicion. Iran’s support for Shia communities and opposition groups in Bahrain, Saudi Arabia’s Eastern Province, and elsewhere raises fears of internal subversion. The scars of the Iran-Iraq War, in which Arab states backed Saddam Hussein, and subsequent proxy conflicts have kept these tensions alive for decades.
Iran’s advancing nuclear program adds a strategic dimension that alarms Arab capitals. Even short of acquiring nuclear weapons, Tehran’s uranium enrichment activities and missile development create the potential for nuclear blackmail or deterrence that could embolden its proxies. Gulf leaders worry about a regional arms race, with countries such as Saudi Arabia, the UAE, and Egypt signaling they would reconsider their own nuclear options if Iran crosses key thresholds. The uncertainty alone disrupts long-term planning and heightens escalation risks.
Geographically and economically, Iran holds significant leverage. Its forces can threaten the Strait of Hormuz, through which a large share of the world’s oil flows. Repeated Iranian threats to disrupt shipping, combined with demonstrated strikes on Gulf infrastructure during periods of heightened conflict, expose the vulnerability of Arab economies. These economies increasingly depend on stability to pursue diversification programs, attract foreign investment, and develop tourism and non-oil sectors. Any major disruption carries immediate costs in higher insurance premiums, capital flight, and lost growth.
Historical context reinforces these fears. The power vacuums created by the 2003 Iraq invasion, the Arab Spring, and civil wars in Syria and Yemen enabled Iran to expand its footprint. While competition for leadership in the Muslim world predates the modern era, contemporary rivalries—particularly between Iran and a Saudi-led bloc—have intensified the contest. Some Arab states have responded by deepening security ties with the United States, quietly cooperating with Israel, and investing heavily in advanced defense systems. Recent diplomatic efforts, such as the 2023 China-brokered détente between Saudi Arabia and Iran, have eased tensions on the surface but have not erased deep-seated mistrust.
Not every Arab state approaches Iran identically. Oman and Qatar, for instance, maintain more balanced relations for geographic and diplomatic reasons. Yet across the region, the core apprehension remains consistent: Iran’s hybrid strategy allows it to erode influence from within, threaten regimes ideologically, and dominate escalation ladders through missiles and proxies.
In essence, Arab states fear Iran not for its conventional army but for its proven ability to wage low-cost, high-impact campaigns that destabilize neighbors while avoiding full-scale war. This dynamic continues to shape alliances, defense spending, and diplomatic maneuvers across the Middle East, making Iran’s regional behavior one of the defining security challenges of the era.
