Every side in every war uses propaganda. Or they keep their mouths shut so as not to let their enemy know if they were/are being successful. It's called "The Fog of War."
After 12/7/41 we knew what our losses were, and they were severe, but did not make them public until we had some good news to report from the battle of the pacific.
That's the way war works. You'll get the good or bad news when the time is right. Not everything can be instant gratification. Yea, I know, that's what we're use to in this day and age. But when it comes to war, sometimes you have to be patient and wait for the President, Generals, Soldiers or Historians to tell us what actually occurred.
Don't look to agenda driven news organizations for facts. Most of the time they are just "Preaching to their Choirs." Sad to say, but true.
