The U.S. and the whole world for that matter has been the subject of extreme media manipulation or pure propaganda. This has been going on for at least 60 years.
Electing a character like Obama shows just how effective it has been.
The History Channel had a program on WWI battles which was actually pretty good. They described one battle won by the Americans with a lot of casualties.
There is a sign at the American Graveyard which says. “America Will Never Forget What You Did Here”. The trouble is, America already has forgotten and I had never even heard of the battle.
