I've been doing a lot of research on wars in the past 40 years or so as I need to find two countries in Europe that would most likely go to war with one another and why. I want it to be a slightly more interesting reason than either ethnic cleansing or imperialism. Ideologies wouldn't work either as europe seems to no longer disagree on them. Is there anything I should read up on or maybe a fiction book that could give me any ideas? I'd also prefer to stay away from Russia, North Korea, China... you know.
