This could be a volatile topic, so I understand if mods shut it down, but I thought it interesting enough to remark upon.

The BR system is abstract enough and good enough at simulation that I think interesting parallels can be drawn to real world events.

I hope I'm not stepping on anyone's toes (since I intend this just for play discussion), but a little piece of strategy that can be learned from the current Russia/Georgia affair, based on a parallel explanation, might be:
1. Gain law holdings in a region of a neighboring country
2. Agitate the attitude of that area in your favor/against your neighbor
3. Spark a conflict with an Espionage action (rebellion or otherwise)
4. Move in under justifications of aiding the people of that region
5. Increase your power there or take control of the provinces themselves

Pretty straightforward, and probably been done many times before in BR. I just thought the parallel with recent real world events was interesting in that it shows the effectiveness of BR as a simulation.
