The US government underestimated Iran's potential to close the Strait of Hormuz in response to US military strikes, according to multiple sources. The Pentagon and National Security Council failed to fully account for the potential consequences of the potential closure of the strait, which some officials have described as a worst-case scenario now facing the administration. Key officials from the Departments of Energy and Treasury, including Treasury Secretary Scott Bessent and Energy Secretary Chris Wright, were present during some official planning meetings but their agency analysis and forecasts were secondary considerations. The administration's efforts to mitigate the economic fallout may take hold within weeks, potentially leading to high-risk naval escorts of oil tankers. The White House praised the administration's planning and was prepared for any potential action by the Iranian regime.
