A Botnet of U.S Military Hosts

Building DDoS bandwidth capacity for offensive cyber warfare operations may seem rational, but this departamental cyber warfare approach would never manage to match the capabilities of the self-mobilizing hacktivist crowd :

"Where’s the enemy, and where’s the enemy’s communications and network infrastructure at the first place? It’s both nowhere, and everywhere, and you cannot DDoS “everywhere”, and even if you waste a decade building up the capability to DDoS everywhere, your adaptive enemy will undermine the resources, time and money you’ve put into the process by avoiding outside-to-inside attacks, and DDoS your infrastructure from inside-to-inside."

Here are related comments on how unnecessary the whole idea is at the first place.
