The ROE are never in place to win any war.
This has been another international police action-limited war in the Korea-Vietnam tradition from the beginning.
Since WWII America does not fight wars to win anymore.....
That's because the winners are the ones smart enough to make up the ROE as they go along, and impose them on the adversary.
"Adapt. Improvise. Overcome."
Either give the troops a free hand or bring them home. Don’t let them be bullet stoppers with little ability to fight back.
