Former Israeli Intelligence Chief Urges Policy Shift Amid US-Iran Deal Challenges

A preliminary agreement between the United States and Iran has left Israel facing new security challenges that require a clear policy adjustment, according to former IDF Intelligence Chief Tamir Hayman. Published on July 2, 2026, Hayman stresses that while the full details of the US-Iran understanding remain unclear, the visible elements suggest Iran gains international legitimacy and economic relief, strengthening the regime despite Israel's concerns.

Hayman highlights that Iran is determined to maintain its nuclear capabilities, as evidenced by its insistence on including nuclear rights in the memorandum and ongoing progress in nuclear development despite limited sabotage operations. The current agreement freezes Iran’s nuclear program at a concerning level, allowing rapid advancement back to a threshold nuclear state if the deal collapses. The Iranian missile program, with over 1,500 missiles capable of reaching Israel, remains unaddressed in the agreement, though Israel’s defensive capabilities are currently strong.

The deal also indirectly supports Hezbollah, which benefits from Iranian backing and American legitimacy, complicating Israel’s northern border security. Hayman calls for advancing the principles agreement between Israel and Lebanon to reduce Hezbollah’s power, emphasizing the necessity of active American involvement to ensure the Lebanese army can dismantle Hezbollah’s infrastructure.

Given these realities, Hayman argues Israel must focus on two primary threats: Iran’s nuclear project and its proxy forces. He advises maximizing oversight mechanisms in the current deal, developing rapid intelligence and operational capabilities to counter any nuclear violations, and engaging diplomatically to shape future agreements. Israel should not abandon the diplomatic arena despite dissatisfaction with the deal, as disengagement risks worse outcomes.

In conclusion, Hayman warns that if the US-Iran agreement marks the end of conflict, it sets a dangerous precedent. Israel must proactively address immediate threats through decisive policy, military preparedness, and diplomatic initiatives, including potential territorial adjustments in Lebanon to stabilize its northern defense line. Any shift in Israel’s stance on nuclear agreements should be an independent decision, not dictated by US policy.
