We know that war against the recognized establishment by networks, tribes and other "non-state" actors has always existed. But, in spite of reading Lind's defintions several times, I just don't understand how it's "generational."

I think Lind looks at the world wearing 4GW glasses, so everything is interpreted in light of his ideas and definition of 4GW. He goes too far, but just because he goes too far is that to say that he isn't right about some things?

According to law, Major Hasan commited murder. That's the way I see it too. But in Hasan's mind, he was a Soldier of Allah. So, some will see it an act of war against the state by a non-state entity. Or, 4GW as Lind defines it.
