[Akira] What would have happened if Akira hadn't been awakened, and the Tetsuo blob-monster was able to run rampant?

My question is aimed at the anime, however I've read the manga as well, and I'd take accounts from both perspectives.

Excerpt from Brigadier General Richards USAF, Classified Report dated December 3rd 2019: The Battle of Neo-Tokyo took three days and ended only after the detonation of 23 high yield ICBMs. In the initial engagement with the anomaly, 37 F-27 Raptors were lost. It was quickly realized any conventional attack was going to be futile. Another, conventional attack was coordinated by PRC air-defense, as initial reports claimed the anomaly was a weapon developed by the Japanese. DARPA quickly surmised without immediate action the anomaly was going to expand uncontrollably. Jets were scrambled and the Pacific Fleet was put on high alert. The initial bombardment proved insufficient to pacify the anomaly. The decision was made that nuclear bombardment was the only option and NORAD moved to Defcon 1. In the aftermath, the Kanto region surrounding Neo-Tokyo was rendered annihilated and Honshu Island uninhabitable.
