A potential US-Iran deal threatens to significantly damage Israeli Prime Minister Benjamin Netanyahu’s long-cultivated political image as the leader uniquely capable of influencing US policy on Iran. For decades, Netanyahu positioned himself as essential to maintaining strategic alignment between the US and Israel regarding Tehran, particularly through sustained pressure and military options. He fostered strong ties with US Republicans and frequently addressed the US Congress to build support. However, the recent interim agreement between Washington and Tehran suggests a reversal of this dynamic, with Netanyahu now compelled to accept a US approach that increasingly disregards Israeli concerns. Analysts note he is caught between domestic opposition to concessions and the risk of alienating the US. The conflict, initially intended to solidify his legacy, may instead be remembered as a turning point in his political influence.
