That album is basically Tragedy's project. He mentored Nore, produced songs, and had a lot more to do with that album than Capone ever did.
The Bridge rappers all beef with each other, but in the end have a catalog of music with one another. Whether Capone snitched or not, who knows, I think he probably did, but it didn't hold up and Killah Black got out anyway.
Prodigy goes in-and-out of periods where he bashes Capone. Sometimes you'll see him posting **** on IG about it. Why Mobb Deep continued to make music with Nore, Trag and Capone even after supposed periods of beef never made any sense. Tragedy and Nore had beef with each other for years after War Report.
All in all, who cares. War Report is a classic album.
