Since this thread got more attention than i expected: I wrote it late at night after some beers, some of the stated facts may not be rock solid or with missing context. So, in no way i can claim it's a 100% correct representation. The idea was not to write a comprehensive history of the conflict but focussing on mentioned map.
I will try to rewrite it in some days and maybe expand it with some relevant points (although it's impossible to cover EVERY aspect, i will have to leave out stuff).
