"I was in Korea in 1960–1961, 18 at the time, when my first sergeant said we were protecting our country, I asked how we were protecting our country thousands of miles away with no ammo!! I was answered with a dumb look; guess we are still not supposed to think." RWK
Exactly, as Marine Corps Major General Smedley Butler, a two-time Congressional Medal of Honor winner, said: "Like all the members of the military profession, I never had a thought of my own until I left the service. My mental faculties remained in suspended animation while I obeyed the orders of higher-ups. This is typical with everyone in the military service."
By the way, it is those who did not fight in WW2, Korea, and Vietnam that are my harshest critics, not veterans of those wars.
