BBC Country Profiles
Great for getting to know your country. I think it's better than the CIA's World Factbook for helping with Country Policy. But check both to be thorough.
Human Rights Watch
They cover every human rights abuse in every country. Don't go here unless you're ready to be informed about the worst that goes on in our world.
UN Documents Search Engine
Thanks to Mission Viejo HS's website, on their "resources" tab, this will help you search for previous UN statements, resolutions, etc. that relate to your topic.
Great for background on a variety of topics and regions.
