But for the men who fight them, the purpose is clear and must remain so.
They fight and often die for their country and their flag. A purpose and cause that is right, even when the leadership is wrong.
Great care must be used when one is critical of a war or a use of military force.
Always.......
That is what a patriot is and does.
When you take a good look at the Vietnam war and put it into perspective. You find that although we technically lost the conflict and withdrew with large losses, we actually won when one considers what the big picture goal was. We stopped the spread communism in it's tracks, not just by that one action, but by a series of actions throughout the world, both subsequent, prior to, and including Vietnam. Cuba being another one.
I am fortunate to have lived through the cold war and to have seen the fall of the "wall". And, I did my part in West Germany while we pressured the Communists of that front of the war in 1970.
Was it worth it?
Sure it was! because we are all free to talk about it now. If we had lost, we would not be talking about this now, or ever.
