What is the much more efficient boundary of government that is not a nationstate ?
Something is going to break. And we generally wake up and fix thing only after things break.
I say another 5-10 manning/snowden type events before we transition from the united states of america to the the united states of earth.
National identities, as complex as they are and as huge an improvement over religions as they are to serve for the above purpose, are still artificial constructs that in many ways create arbitrary boundaries, introduce and perpetuate differences that are not necessary to exist between people and in some cases have even been manipulated and used by governments for political reasons.
Last I checked they immigrated too.
But if a person says the phrase "I'm American", what's your first guess - that he is referring to the USA, to Canada or to Mexico?
Speaking as a Canadian, I do not call myself an 'American', even though my country is certainly part of North America.
I understand that "Americans" is a shorthand for "USA Habitant", in the minds of a lot of people, mainly because USA is the dominant culture in this side.
But is like ask: "I'm Asian" and asume is about a chinese.
