The US

Here are some links for a few streams on US history:

Here is one on the history of the expansion of the US territory.

Here is a satirical animation on US history and gun ownership.

Finally, here is the perspective of Howard Zinn, the author of A People's History of the United States.

This is just to give us the initial momentum.  We do not have the limit the scope of our discussion to US history; we can also talk about issues such as education, culture, etc.
