Turkey would win. I'm imagining that natural country strengths would come into play, and I like to think that Turkey is my strongest country.
If I take Octavious' suggestion and have the diverging point two weeks ago, then simple differences in when I woke up, what I've eaten, and whether or not I have had any caffeine might also influence the results.
It would be weird because I imagine the seven of us would be online roughly the same times, so there'd likely be a flurry of activity and simple things like who talks to who first might be quite influential. In that case, England might have an advantage simply because if the seven of us started talking to countries left to right on the tabs at the top then England might get plans in motion the earliest, and most likely with France as that would be his leftmost tab.
Cyrano, I get what you mean, but I don't think it would really work like that. I don't actually think I can predict what I'm going to do when I'm the same person, let alone if I'm in a separate body and mind. There would be a parallelism in the sense that we would have a tendency to think the same things, but I don't think you'd be able to predict what the other yous would end up doing. Not because of free will, but because of sheer uncertainty due to random influences and insufficiently powerful introspective abilities.
You don't really know yourself *that* well. You only know who you think you are. A lot of ego and rationalization comes into your perception of yourself, such that in many ways, others may catch a smidgen more insight into who you are than you might due to your obvious bias. If you actually met yourself you might be unpleasantly surprised by your personality, not including the general shock of meeting yourself, you might dislike your other self as much as people often dislike hearing their own voices as everyone else hears them. When I say "you", I don't mean you in particular, but the equivalent of the third person "one".
