This is the catalyst OP neglects to mention.

Stocks reaching record highs whilst bond markets are tanking indicates the ponzi is becoming unsustainable,that even the printing of trillions of $fiat can't prop it up indefinitely.

Best the US buys those high tech weps with free fiat whilst it is still able to.

But there will be no defence against weapons capable of causing great 'natural' disasters,which is how I believe US soil will be attacked.

OP is right tho,individuals should be preparing their families and themselves for massive social unrest,and war,as experienced by previous empire collapse.
