This is our world we should know its history. Obviously you can't include everything. People wanting more specific foreign history classes like the history of Germany, the history of Spain,...Should be able to take those as electives but everyone should get to know world history. This is our world afterall.
I don't think it should be mandatory for students to take foreign history classes. I understand that it's important to know history, but there is only so much time that students have to learn. There are more important things that they need to spend their time on, such as math, science, and the history of their own country.
