Hmmm...That would be really hard for me to do. Way back in one of my political science classes we did a simulation where students represented nations and the teacher presented us with problems to deal with.
I was the US and one of the situations was that Kim Jong Il had died (this was obviously before he actually died) and no one knew what was going on in N. Korea. They were being especially tight lipped about it. They wouldn't even tell the China or Russia groups what was going on.
So China and Russia approached me with a plan to take out N. Korea. We brought in the UN and Japan and totally smashed N. Korea!
