Politicians love to start foreign war adventures as proof of their giant masculinity.  After the slaughter begins, they retire to lifetime golden government compensation and massive speaking fees to bask in their glory.  Meanwhile, no following politician knows how to stop it all since this is no longer giant battlefield clashes but never-ending guerilla warfare.  The feudal structure of modern military training and operations continue to fight with WWII tactics and constant demand for bigger and more expensive weapons.  Meanwhile the humans exposed to the actual war return from the carnage damaged in mind, spirit, and body.  The war machine top dogs continue the mantra:  Trillions for armament, pennies for human recovery.  The brainwashed populace continues to support war on the backs of volunteers and private corporate mercenary armies.  "Thank you for your service" is the lame utterance of those unknowing or truly caring for the detritus of war.
