The only anchor in reality appears to be Biden suggesting that they knew how to take it out which seems like a pretty weak place to build a large story.
What I find particularly odd is that this entire thing appears to be based on a single, unnamed source "with direct knowledge of the operational planning".
It's not entirely fiction such as, "And then Biden sacrificed a peahen, waved his magic wand, and spoke the incantation and the pipeline exploded!" The events, organizations, equipment, and strategy described in the document is all real-life stuff!
