In the article it states the average lead time for a Pentagon-organized cyberattack is six months.
The main point of the article is that this guy is basically trying to push the Pentagon to be more like him, a guy who took personal offense when a North Korean hacker tried to drive-by hack him then took the entire country offline without first considering whether or not they might retaliate against an actual lone wolf attacker, or whether this is a rational response as an individual to the existence of organized nation-state attackers.
Basically, he’s lucky the Pentagon took an interest in him. The article points out that the officials he shared his attack with were well aware the main reason they couldn’t do something similar is literally just bureaucracy. He’s not offering anything new on a technical level, he just wants the Pentagon to shoot from the hip more often and worry less about the consequences of their actions.
TBH, probably everybody in the world would prefer the slower, less aggressive Pentagon we have now rather than one that goes around picking fights with every nation-state and group that pisses it off for like, any reason.
