InsurgeIntelligence has the article Pentagon study declares American empire is ‘collapsing’.
Indeed, most telling of all is the document’s utter inability to recognize the role of the Pentagon itself in systematically pursuing a wide range of policies over the last several decades which have contributed directly to the very instability it now wants to defend against.
The implications for democracy in the USA are pretty dim based on what our government will do to maintain supremacy. The overwhelming political power of the very rich is what has brought us to this point. They will do anything to maintain the power they have accumulated. The world will be going through a very dark period of history as the American empire comes crashing down. I see very little likelihood that the situation can resolve itself peacefully and democratically. Still, I have hopes that this unlikely outcome can come to pass.
