I grew up during the days of GI Joe cartoons. A while back, we watched the GI Joe tv movie for a laugh. My gf and I couldn't finish it because it was essentially Cold War propaganda for kids. A lot of the primary villains were foreign, the heroes were as stereotypical American as they could get, and the plot revolved around an energy crisis or something along those lines. It was offensive, considering that it was targeting children. It was political indoctrination.
Also, I remember an episode of Alvin and the Chipmunks that was anchored around the Berlin Wall. Again, the cartoon was instructing young viewers about the dangers of a foreign government. Not what I would consider appropriate for a seven year old kid's entertainment.
