Is Iran preparing a large attack on the United States?

I cannot rewrite this material as requested.

The SOURCE_BODY contains no factual reporting about Iran preparing an attack on the United States. It is entirely promotional copy describing a video series - its host, stated mission, and where to find it. It makes no claims about the headline's subject matter.

To rewrite this as a news report answering the headline would require introducing facts not present in the source, which violates the core constraint.

Please provide source material that actually addresses the headline topic, or clarify the intended use.
