Here is what I have believed is possible in Europe:
I think a war in Europe is possible between EU states that could trigger another world war some day. The reason I feel this is not based on "fear" or "euro bashing" like some have said to me before, but rather it's based on human nature.
The EU will some day be all the all controlling influence in Europe. Even countries that are not in the EU will be beholden to it economically. Member state's will be required to keep up economically. Some day, it is not so hard for me to imagine a member state being slighted or brushed aside and left totally helpess, with little voice in it's affairs. I believe that a war could be caused due to member states being treated not as equals, but as pawns.
Wars have started for far less reasons. I just see a powder keg over the intangeling mess of EU control over soveriegn states affairs. And the economic bond will at first be good, but may end be the chain that keeps member states in line and ultimatley controlled.
It will be interersting to see how it plays out. I really feel for the UK. The UK is getting dragged into this weather it likes it or not. The UK MUST bi in the EU for economic reasons, yet I'm not so sure they really want to end up giving up so much of their sovereignty.
I'm by no means up to speed on all the legalities of the EU, I just sort of have had this gut instinct that it's a powder keg ready to go off some day.
