The recent conflict involving Israel and the United States against Iran commenced with Israel lacking a pragmatic strategy for regime change, relying instead on "wishful thinking" regarding a popular uprising rather than concrete intelligence. Despite nearly two weeks of intensive bombing raids and the assassination of Ayatollah Ali Khamenei, the Iranian regime has demonstrated resilience. The long-term success of this conflict, should Iran's new leadership maintain power, will largely be judged by the fate of 440kg of enriched uranium, enough for over ten nuclear warheads, which was buried under a mountain by US strikes last June.

According to former and serving Israeli defense and intelligence sources, the critical measure of success is either the removal of this nuclear material from Iran or the establishment of a regime deemed trustworthy enough to safeguard it securely within the country. Hardliners in Iran have historically viewed a nuclear deterrent as essential for the Islamic republic's survival, a belief likely reinforced by the overwhelming military dominance displayed by US and Israeli forces during the war, especially if the current regime endures. Discussions prior to the conflict had explored proposals for Iran to surrender the enriched uranium to another nation, and the US is reportedly contemplating a high-risk mission to secure it.

The assassination of Iran's supreme leader, Ayatollah Ali Khamenei, has further complicated the nuclear threat. While Khamenei had dedicated substantial resources to a program capable of military application, he had consistently refrained from ordering the final stages of weapon construction. The intentions of his son and successor, Mojtaba Khamenei, remain less clear, prompting concern among former intelligence officials who fear he might rapidly pursue a nuclear weapon. While the extensive damage from bombing could delay development, a political decision to proceed with a bomb would significantly escalate the long-term threat to Israel.

Following the Hamas-led attacks on October 7, 2023, Israel's military strategy shifted to prioritizing the swift elimination of immediate threats, such as Iran's ballistic missile program. The two-week bombing campaign has significantly degraded Iran's military capabilities, targeting missiles, launchers, military industrial supply chains, and key political and military personnel. This aggressive approach reflects a "zero tolerance" policy within Israel, widely supported by its military establishment and society. Despite the military's success in achieving most operational objectives, experts like Sima Shine of Mossad contend that regime change through external bombing is highly improbable, describing it as "wishful thinking." Initial calls for regime change by Israeli Prime Minister Benjamin Netanyahu and Donald Trump, potentially influenced by Trump's perceived success in Venezuela, proved unrealistic for Iran.

A significant consequence of the bombing campaign has been the severe damage inflicted upon Iran's rich cultural heritage. The governor of Isfahan denounced the actions as a "declaration of war on a civilization," citing damage to numerous historic sites. Among the most severely affected are Tehran's 14th-century Golestan Palace and Isfahan's 17th-century Chehel Sotoon Palace. Although not directly hit by missiles, these UNESCO World Heritage sites suffered shattered glass, dislodged tiles, and masonry due to shockwaves and debris from nearby blasts. Other damaged sites include Falak-ol-Aflak Castle in Khorramabad, where departmental offices and museums were destroyed, and 19th-century mansions in Sanandaj.

Iran's Foreign Minister, Abbas Araghchi, publicly blamed Israel and criticized UNESCO's "unacceptable silence" regarding the destruction, particularly after the coordinates of these historical sites had been shared among warring parties and "blue shield" signs, denoting cultural treasures under the 1954 Hague Convention, were displayed. The US Committee of the Blue Shield expressed dismay over the US defense secretary's declaration of "no stupid rules of engagement," cautioning that such disregard for international and US laws on hostilities could constitute war crimes. The organization underscored that the destruction of cultural heritage is irreversible, erasing identity and shared memory without justification by military or political objectives.

While the immediate military achievements provide Israel with short-term security and a greater capacity to project power, the war carries substantial long-term risks. If the Iranian regime survives and retains the enriched uranium, a "new weaponization race" is anticipated, posing a renewed and potentially greater nuclear threat. Furthermore, Israel's firm embrace of military power as its sole path to security could lead to its isolation in the Middle East and globally, as other regional and international leaders grapple with rising fuel costs and economic instability exacerbated by the conflict. The war, which began in Gaza and has expanded to multiple fronts, therefore presents a complex and potentially perilous future for the region.
