Interesting read with a number of insights and creative ideas, but it was still locked in to a scenario of relatively symmetrical, state-versus-state war. It's debt to Tom Clancy is too obvious and dates it.
It would be more interesting as a work of futurology if it looked at say conflict between states and state-like entities, 'maskirovka' - 'masked war' or a 'warm war' over resources in the Arctic.
A TED talk by policy analyst Bernadetta Berti here sums up why fighting ISIS is going to be a protracted affair and why its going to require different thinking. In short, you can't fight the Mafia or a cult with railguns.

War is Boring can be a bit shallow, but a search will bring up more material:

Indeed, there is a fictional exploration of hybrid war, by one 'Natan Dobuvitsky', whose real name is Vladislav Surkov, former Deputy Prime Minister and current chief advisor to Vladimir Putin.

Peter Pomerantsev, who spent several years in Russia has written this profile of Surkov:

It (and a related nonfiction book, 'Nothing is True, Everything is Possible') deals more with how internal control is exercised, but as Orwell wrote, War is Peace - and hybrid war is the expansion of politics.
