Israel’s forces are vastly superior to Iran’s when it comes to technology. Iran, however, has massive stockpiles of cheap but effective weapons in its arsenal.
Since 2022, Iran has provided more than 1,000 Shahed-136 UAVs, as well as Shahed-131 and Mohajer-6 UAVs, to support Russia’s invasion of Ukraine. In May, Iran began assisting Russia in establishing a Shahed-136 UAV production facility in Russia, according to the DIA. So it’s safe to assume that Iran has hundreds if not thousands of one-way drones in its inventory to attack Israel.
Israel would counter ballistic missiles with its Arrow interceptors and drone attacks possibly with David’s Sling air defense systems and perhaps with a system called Drone Guard made by ELTA Systems.
Who are their allies? What roles might they play?
Iran’s most important allies are the Shiite militias in Lebanon, Iraq, Syria and Yemen that it supports with money, weapons and training. The Lebanese militia Hezbollah would be positioned to play the most significant role. It’s fought repeated battles with Israel and has been regularly firing missiles, mortars and rockets into northern Israel since war broke out in October between Israel and the Iran-backed militant Palestinian group Hamas. Hezbollah’s arsenal contains more than 70,000 rockets and missiles, including long-range and precision-guided missiles, according to Israeli intelligence.
An escalation of its attacks on Israel could test the country’s defenses at a time when it was also confronting Iran and Hamas.
Iran’s only state ally in the Middle East is Syria. The government of President Bashar al-Assad would be unlikely to be of assistance given that it’s still struggling to gain control over the entire country following the outbreak of civil war in 2011.
Iran has good relations with Russia, though its war in Ukraine would likely limit its ability to help, and with China, which has bought Iranian oil though it remains sanctioned by the US and allies.
Israel has the US on its side. Already the US is expediting shipments of munitions to Israel, to help it fight Hamas. Among the US forces in the Middle East region are two Navy destroyers that moved to the eastern Mediterranean in early April, according to a Navy official: the USS Carney and the USS Arleigh Burke, both capable of air defense.
Early in the Israel-Hamas war, the Pentagon moved its newest aircraft carrier, the Gerald R. Ford, and its battle group into the eastern Mediterranean. It has since returned home. The Dwight D. Eisenhower carrier strike group is on its way from operations against the Houthis. Each bristles with F/A-18E/F Super Hornet fighter jets and other advanced aircraft. In addition, 2,000 Marines were put on heightened alert for potential mobilization.
How might Arab states react?
An Israel-Iran war would put many of the countries in the region in a difficult position. Four Arab countries made peace deals with Israel in 2020 via the so-called Abraham Accords. Their distrust of Iran was part of what brought them together. But it’s unlikely any Arab state would stand with Israel in a confrontation against a fellow Muslim country, let alone one as powerful as Iran.
Iran and Saudi Arabia last year restored diplomatic relations after a seven-year freeze. Saudi Arabia has been exploring the possibility of normalizing ties with Israel as part of a broader deal in which it hopes to attain US security guarantees, and it would likely try to avoid become embroiled in the conflict.
