I was not aware that the POTUS had any specified "core values." Perhaps you could point me to that.
As for the military, you might want to be more specific. While there are certainly "bad eggs" in the military (show me a group of close to two million people--active and reserve--anywhere that doesn't have some "bad eggs"), my own experience is that the military does a pretty good job of holding to it's "core values" (said to me by my TI on the day I reported for Basic: "I don't care what you think you joined the Air Force for, from this moment on, you are here for three reasons--Duty, Honor, Country.")
You totally missed my point.........
"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
Regarding military, I'm talking big picture, not servicemen & women, they simply follow orders. Examples? Ruby Ridge & Waco come to mind right off the bat.......let me know if you want more.
