You're all off to a good start. I've sent you all some suggestions about what to look at next, but here are some other things:
Check for any significant wars or events that have defined the conflict.
See what you can find out about the leaders of relevant groups or governments: names, backgrounds, etc.
You'll probably need to go beyond the CFR site... now would be a good time to take note of the sources you find useful... they're likely to continue to be useful as the year goes on!
