I love how these junior officers write as if the Pentagon is oblivious to the threats they're identifying. Gee I think the Joint Chiefs have access to all this information and a whole lot more.
The top pentagon flag officers do have a reputation for fighting the previous war over again, right?
Might be these junior officers see that and are trying to break out of the box. After all, it will be their ass on the line, not the career brass in the pentagon.
