>I wouldn't describe integrating further to the point of becoming more like the US as "unstable".
More like the US, as-in a country? So also more like Germany, China, South Africa, etc. You are making a false equivalence - being like the US in one extremely non-US specific way does not mean you must be like the US in every other way.
I'm not sure you even understand what I'm saying - this has nothing to do with the US vs. the EU or if the US is reliable.
I was referring to the possibility of the EU becoming a federal union which acts like a country. Yes, like the US and Germany, but unlike China and of South Africa I don't know enough to say.
