Former Mossad Chiefs Stark Warning: Why No Agreement Can Change Iranian Ambitions
Former Mossad Chief Yossi Cohen warned that regardless of any potential ceasefire or agreement, Iran’s fundamental objectives remain unchanged and dangerous.

During a recent memorial service for the families of fallen soldiers, Yossi Cohen, the former head of the Mossad, issued a stern warning that diplomatic agreements with Iran should not be viewed as a guarantee of peace. Speaking at the Museum of Tolerance in Jerusalem, Yossi Cohen addressed the ongoing negotiations with Iran, which he described as being at a critical point.
He urged the public and decision makers alike not to fall into the trap of believing that the current diplomatic maneuvers will alter the regime’s trajectory. He stated clearly that Iran will continue to deceive the international community, and that Israel must not fall into the mistake of trusting the regime or resting on its laurels. According to Cohen, no agreement or ceasefire has the power to change the fundamental and foundational goals of the Iranian leadership.
Cohen reflected on the significant military and intelligence achievements of the Israel Defense Forces and the intelligence community during recent operations, which he noted demonstrated Israel’s immense capability. However, he maintained that these successes, while significant, do not signal the conclusion of the war. He emphasized that the State of Israel will continue to require sacrifice, determination, and boundless Zionism to ensure its long term safety.
The event, organized by the Organization of IDF Widows and Orphans, served as a solemn reminder of the human cost of the ongoing struggle. Yonatan Riss, the CEO of the Museum of Tolerance, echoed these sentiments, noting the society’s responsibility to strengthen values of tolerance and unity in the wake of such profound loss. The message from both leadership figures was clear: while diplomacy is ongoing, the reality of the threat posed by Iran remains, and the nation must remain vigilant and united to protect its existence. The Ministry of Diaspora Affairs added that the event was broadcast in English, allowing Jewish communities across the world to participate in the solemnity and strength of the Israeli commemoration.
