NATO is a self-perpetuating bureaucracy. First and foremost the member ‘employees’ want to keep living life large on other peoples (our) money. Anything else is accidental.
I’ve talked with a few US Army NCOs and officers who were stationed in Belgium at NATO HQ. Sounds like the non-Americans are out for the day generally by noon, not really having done anything in the preceding hours anyway. Thank God the Soviet hordes never invaded.
