Prediction: Israeli Terrorists detonate a dirty bomb in the West, and use their control of media and Hollywood to create a convincing narrative of it being Iran's. That will manufacture consent and pretext to nuke Iran, or better yet, get America to do it.
Being the only country with illegal nukes, they are on a short list of 1 to be the source of a dirty bomb. So yeah it would be a tough sell. But they've convinced the world of weaker false narratives before. Since they love to play victim, they might even nuke-lite themselves Oct 7th style.
