It could be that all awful dictators are frustrated artists - Mao with his poetry and Mussolini with his monuments. Stalin was once a journalistic hack, and I can personally testify to how frustrated they are. Pol Pot left a very edgy photo collection behind. And Osama seems quite interested in video.
I think people should look at learning about Native American history the same as visiting Washington, D.C., and seeing the monuments there. It's all part of the package.
People should have freedom in their pilgrimages and tours. They should come and visit historical monuments and sites - let's say the sites around Iran - where they can easily engage in wide- scale contacts with others.
