That is how I read it!
Maybe I an wrong.
XD3 seeks truly innovative, revolutionary approaches to DDoS defense, as opposed to incremental or evolutionary advances to current art. Proposals must clearly articulate why their solutions represent a major advance over existing techniques.
Responses to DDoS attacks are too slow and manually driven, with diagnosis and formulation of filtering rules often taking hours to formulate and instantiate. In contrast, military communication often demands that disruptions be limited to minutes or less.
The above is stated at the start of the document.
I cannot see how to deliver this without something more aggressive simple filtering/blocking etc.
The rest is just extrapolation based on the fact that we are told regularly that such attacks are being made by 'nation states'.
Countermeasures will be resisted, then follow the bouncing dot .......
