No, no he didn't. From what I can recall, the rules in combat are kill the enemy, save yourself and your brothers, but definitely kill them.
Are you sure about that?
I'm pretty sure that hasn't changed since forever.
We could always train, and engage when engaged. After the Bush years we figured it was time for someone else more local to engage, Trump is changing that, now he is putting our neighbor's kids on the front line, or at least he wants to.
Apart from all the nonsense you spewed, what has changed is the 'Rules of Engagement'. We are killing more civilians.
That should win hearts and minds. Be prepared for two more generations of war unless something changes, and not in a 'Trumpian' way.
Right now with have children of veterans of the Mid East wars serving. It won't be long before we have grandchildren.
I remember a book with a never ending war, but you probably don't do much readin'.
