Cav Guy. Read his book a long time ago; agreed with parts and not with others. I do strongly agree with this statement of his you quote:
"the fact is that we have to establish a military and civilian establishment which can fight and win any war, on any battlefield, anywhere in the world. That will require dominant symmetric/conventional/nuclear capabilities and asymmetric/irregular/counterinsurgency capabilities.
Anyone who agrees with me is bound to be thinking correctly...

Or is that I agree with him so I must be thinking correctly...

Either way, he's right.

P.S.

I have no hangup on hybrid war as a term; I just point out that as a practical effort, it's been around for years and thus is not 'new.' McCuen is correct, we have not dealt with it at all well and we need to be able to do that. No radical reforms are necessary, just common sense improvements -- and the civilian policy establishment is a big part of the problem.
