Are the balkans not part of what has traditionally been considered Europe? I seem to recall a little conflict involving ethnic cleansing back in the late 90's...

Also, I understand that Russia is considered less and less "European" with each passing year but the Ukraine and Russia (or at least all of its centers of power) are located within the European continent by definition. There's also the issue of the IRA's war against Northern Ireland and the UK as a whole, while that conflict doesn't meet the commonly agreed definition of "traditional warfare", it was the very template every modern insurgency bases itself upon. In a sense that was a war by any modern definition since traditional warfare seems to have become a relic of the past.
