How Israel and the US Dismantled Iran’s Strategic Architecture

The death of Iran’s Supreme Leader did not happen in isolation. It was the culmination of a multi-year strategic campaign by Israel and the United States to degrade Iran’s military capabilities, dismantle its regional network, and ultimately strike at the leadership itself. Understanding that campaign helps explain both how Iran arrived at this moment and what its options are going forward.
The process accelerated dramatically after Hamas’s October 7, 2023 attack on Israel. What followed was not just a war in Gaza but a systematic effort to roll back Iranian influence across the region. Israel’s prolonged campaign against Hezbollah effectively destroyed the organization’s command structure and much of its military infrastructure. Iran’s most powerful and capable proxy was reduced to a shadow of its former self.
The June airstrikes marked a qualitative escalation, targeting Iran’s military infrastructure and nuclear facilities directly. Iran’s air defense systems proved far less capable than its leadership had projected, and the strikes exposed the country’s vulnerability to Israeli air power. The claimed obliteration of nuclear sites, though disputed by subsequent IAEA observations of resumed activity, sent a powerful message about what military force could accomplish.
Saturday’s airstrikes, which killed the Supreme Leader, represent the logical endpoint of this escalating campaign. Targeting a sitting head of state crosses a threshold that has few recent precedents in modern international relations. The decision to do so reflects a judgment that the risks of killing Khamenei were outweighed by the potential strategic benefits.
Whether those benefits materialize depends entirely on what happens next in Tehran. A weakened, internally focused Iran would vindicate the strategy. An Iran that emerges from the transition more aggressive, more willing to develop nuclear weapons, and more unified against external enemies would represent a catastrophic miscalculation.
