In all-out war where you have an enemy who wants nothing more than to kill as many of your as he can, and wants nothing more than to destroy your way of life...you have to take the steps necessary to preserve your way of life. That does not mean you enjoy it, and it does not mean you sadistically torture or maim prisoners for the sake of the sadsim.
Like I said, ask WW II vets who fought German spies posing as US soldiers in the Battle of the Bulge. Or ask US Marines and Army and Navy personnel who fought the Jpanese on ISlands like Tareawa, Guadalcanal, Okinawa, etc. They are not proud of what they had to do to win...but they did it anyway so we could sit here in the peace and comfort of our homes and freedom and theorize about it.
West took responsibility and is willing to be accountable for what he did. He knew it crossed a line. There are mothers, fathers, sisters, brothers, relatives and friends whose sons are in all likelihood alive today because of what he did who are glad he crossed that line. Stack that up to a few bruises and a deflated ego. Ask those parents how they feel...better yet, imagine your own son, daughter, brother, friend and tell me you would willingly sacrifice their life and liberty over the minor infraction of the rules Col. West made. I would not.
Our service personnel have been put in the position to do much worse in the past...in war, they probably will have to do so in the future. I oray to God that they will have the strength and the wisdom to do what is right, however difficult, to preserve liberty and our way of life.
