I don't understand why you made EU and NATO instead of european civs. The civilisations of europe are not nearly as merged as you portray them to be. They each have independant leaders and politics, and furthermore, if NATO declares sanctions or war, not all nations go through with it. Just look at Iraq. My colledge studies have just lead me to read a lot about the EU and the EU you describe, as a single nation without teritorial souverenty will not come to be in many years (if not decades). I don't realy see how they could all count as the same nation.
