The current US government debt has nothing to do with Keynes. The current debt is the result of our ruling classes thinking they could have endless multi-front war and tax cuts at the same time. If this was a Keynes debt it would be spent on massive infrastructure projects within the US, to make our economy much more efficient.

Furthermore, you probably do not remember this, but the Clinton administration was paying back the debt and had America on a path to being debt free. But Bill Clinton, scumbag as he was, wasn't stupid. The wars he started were very short and very cheap.
