Nearly a fortnight into the US-Israeli war, American intelligence assessments suggest there is no immediate indication that Iran’s ruling system is close to falling, according to two sources familiar with the matter.

The military campaign has killed a number of senior Iranian figures, including the supreme leader, and has also weakened parts of Iran’s missile arsenal. Even so, the assessments indicate that the government’s hold on power has not yet been seriously undermined.

In recent public remarks, officials in the Trump administration have sought to present the war’s aims more narrowly, focusing on reducing Iran’s missile, nuclear and naval capabilities. They have suggested any regime change would be a consequence of the fighting rather than its central objective.

However, Trump has also pointed to the nature of the government in Tehran when explaining his decision to launch the war, referring to the country’s leadership as a terrorist regime that has been in power for almost half a century.

On the opening day of the conflict, he urged Iranians to rise up against their rulers. Since then, he has also said Iran must offer unconditional surrender before the attacks can stop.

At the same time, his aides have indicated that any declaration bringing the war to an end would come from Trump himself, rather than from the Iranian authorities.
