I can tell you about one of the smallest federal country involving only 2 nationalities, that are exteremely similar, understand each other's language, even shared part of their history, and it still fell apart. Of course I am talking about Czechoslovakia.
I think it fell apart because they had been forced to be together for a long time against their will. Had they not wanted to be seperated almost as much as being free, I think they would have adjusted and worked it out. As it is, they'll probably end up together in the EU.
It may happen with EU, if the bureaucrats get their way of usurping the power of the member states, increase their budgets, add very big dissimilar (=poor) countries (Poland, Rumania, possibly Ukraine, Belorussia, Turkey, or Russia itself.
There are too many benies to being in the EU. Overtime, I think it will become like the US of A. The hardest part was getting the Germans to give up the Deustchmark...... I think its all downhill from there. <g>
