I discuss the possibilities of America relinquishing its global ambition to reduce its footprint to a regional hegemon in the Western hemisphere. The new technologies of AI, UAVs and hypersonics rather easily challenge the spending paradigms and mission architecture of the American armed forces.

There are no near-peer competitors, every nation on Earth is now a peer to modern western war machines.

America boasts a magnificent 20th century war machine is not fit for purpose for 21st century peer warfare.

The crossroads is chock-full of landmines.
