Israel sees Iran as an existential threat. Israel has accused Iran of harboring genocidal intentions, while Iran has accused Israel of conducting a genocide in Gaza. Consequently, Israel has sought sanctions and military action against Iran to stop it from acquiring nuclear weapons.Did Iran pose an imminent nuclear threat to Israel? Israel's military superiority in the Middle East comes not just through its conventional arsenal or the backing of the US, but from the advantage it has that no other country in the region does: nuclear weapons.(Syria was often called Iran's "closest ally", the Arab nationalism ideology of Syria's Baath party notwithstanding.)Iran is a major regional power, due to its large reserves of fossil fuels, including the world's second largest natural gas supply, third largest proven oil reserves, its geopolitically significant location, military capabilities, cultural hegemony, regional influence, and role as the world's focal point of Shia Islam.Iran boasts a large standing force but also relies on proxies and undercover operations that have been severely disabled in recent months by U.S. and Israeli actions. Israel, meanwhile, relies on both subterfuge and robust regular ground and air forces that are apparently unmatched in the region.
