Europe

[Sarmatian]

But as a sovereign nation you can change that by yourselves.

Can you really? Let's take a not so hypothetical situation. Germany doesn't want Ukraine or Georgia in NATO, because of the simple fact that it will worsen relationship with Russia. Doesn't matter if it is right or wrong or if you agree with it or not personally with this German policy, this is a point where German government and American government disagree. Yet, America is pushing and inviting Ukraine and Georgia at NATO summits, having NATO exercises in Georgia and blah, blah. Naturally, this worsens German and Russian relationship, precisely what German government didn't want.

Europe wants alternative sources of natural gas and oil. Not just because of the political reasons but diversifying your suppliers base is always good. The only country in the vicinity with enough gas is Iran. Europe wants it, US says no. Instead Europe is forced to wait for the eventual Nabucco (which would be US sponsored and controlled), which might never happen as there aren't enough reliable sources of gas.

You may think it's all worth if it will keep America on your good side or that America deserves some leniency because they are investing so much in NATO or whatever but don't kid yourself. By being in NATO and by being dependent on American foreign policy, European countries already surrendered part of its sovereignty, which you treasure so much and are worried that EU will steal from you.

There are only two truly sovereign countries in the world - USA and China. Russia comes close, then come other bigger countries, like India. Then there's a decent gap and then larger European nations come into play. And with how things are developing in 21st century, that gap will become bigger and bigger.

No, your entire foreign policy will be dictated by a larger power - the EU. The point is that right now you have a choice whether you want to go with America or not, and under the EU you will have none.

That's true somewhat. Now you don't have a say in what will happen but you can agree or disagree, which will be duly noted and archived and it will still be happening, whether you like it or not. That's in the case of bigger European countries. In the case of smaller countries, even that is not true. Czech politicians openly admitted that the main reason Czech recognized Kosovo is immense pressure from the US. In the case of a strongly federal EU you will have less freedom to agree or disagree but you will have a say in what's gonna happen.
