Iran will go to nuclear war with the US if prompted.

Recently, inspectors from the International Atomic Energy Agency discovered that Iran had enriched uranium to a level just shy of what is generally considered weapons grade. Like many findings before it, this revelation underscores the need for a new U.S. and European policy toward Iran. The two most important and immediate steps in that process are clear by this point: Washington and its partners need to move on from any remaining plans they might have to resurrect the 2015 Joint Comprehensive Plan of Action (JCPOA), namely by activating that accord’s “snapback” mechanism; and governments must heighten their efforts to deter Iran through credible threats of military force.
In addition, the United States needs to coordinate closely with international partners on how they would jointly respond to contingencies that are looking increasingly likely, such as an Iranian nuclear breakout or withdrawal from the Nonproliferation Treaty (NPT). With Washington perceived as reluctant to act militarily in the Middle East, Israel perceived as lacking the capability to act, and much of the world distracted by the Ukraine war, Tehran may feel that it has a short window in which to develop nuclear weapons, lending the issue renewed urgency.
