The collapse of the Islamic Republic in Iran would be a strategic and economic turning point for both the United States and Israel, while triggering deep political repercussions across Europe for years of failed policy toward Tehran.
STRATEGIC AND SECURITY IMPACT
For Israel, the fall of the regime would remove the core existential threat it has faced for decades. Iran’s clerical leadership openly calls for Israel’s destruction and bankrolls a regional terror network built around Hezbollah, Hamas, and allied militias. Without Tehran’s ideological leadership, funding, and weapons, this network would rapidly weaken, sharply reducing the risk of a multi-front war and neutralizing the nuclear threat directed at Israeli cities.
For the US, regime change would represent the single greatest defeat of state-sponsored radical Islam in modern history. Iranian-backed attacks on US forces in Iraq and Syria would decline, regional escalation risks would fall, and Washington’s deterrence credibility would be restored after years of inconclusive diplomacy.
