Ha! You haven't been to Watsonville, California or just about anywhere along the border with Mexico, have you?
Things tend to be pretty ok in western europe where most can agree on english, but don't forget that a large part of europe was behind the iron curtain and didn't get to learn english until 1989. The majority of people in the east doesn't speak any english at all.
It is only about 60 minutes from Silicon Valley and yet has more culturally and linguistically in common with Mexico in many ways.
The question is not if there are enclaves of other cultures and languages within a larger body of uniform people since on a small enough scale you will always find enclaves: Chinatown, Little Italy, or Kreuzberg in Berlin[2] but how uniform the population is. No population is truly uniform and I don't think anyone pretends that West-Coast Americans and East-Cost Americans are the same as Texan, but I dare to postulate that a common overarching government and a common official language leads to a greater degree of uniformness than 20+ official languages and a loosely knit set of contracts. A norwegian is most likely more different from a greek than a New Yorker from a Californian.

And I'm sure if you live in Watsonville, California, you can get your tax forms in English, right? This is definitly not the case within the whole of the EU and the EU offical languages. (e.g. someone in Ireland could not get their tax forms in Swedish).
The bigger lesson is, political boundaries suck at defining people or culture.
If you live in a larger urban area in the US, odds are that you can encounter several dozen languages in a day.
However that's not at all like the European Union which has to publish all EU Directives in 23 languages, and each country has 1 or 2 or 3 or 4 official languages for their region. In the USA, English is the lingua franca, and official stuff can be done in English. There is no language that you can use all over the EU that will work in all (or sometimes any) official capacity.
Three to five separate languages per day, as you would encounter in any other moderately multicultural/multinational locale? Yeah, any large urban area will do that.
If I drive 1000 km to the southwest, I'm still in Texas... :) If I wish to drive to the nearest ski resort, I spend most of the drive time getting across the damn state! If I want to hear about 40 different languages, I just go to the nearest shopping mall or to the cafe in the next building.
You've classified "Americans" as one group when your really talking about "American Nationalists". It sounds like your attributing nationalist propaganda you see on Fox News to all Americans. This is also a great example of state/city variation. Living in Boston for 7 years I can probably count the number of times I've heard someone talking about "The American Way" or using the term "Unamerican" on one hand. One week long trip to Texas and you hear it a dozen times or more.
I've met plenty of Europeans who were incredibly nationalistic from France, Great Britain, Austria, Czech, etc. and they are extremely vocal and proud of their national heritage/identity. They love telling people that they're French, English, Austrian, Czech, etc. but they never claim to be European.
Similarities could be drawn between the individual European countries and US states/regions (Texas is a prime example).
Uhm, which was my point exactly?
The problem is that it has taken a convergence of demographic tip-over into a mostly urbanized population and a major political/economic/cultural crisis to stop large portions of the American population from deluding themselves into thinking of America as Eagleland.
I hear you and partly agree, but the comparison is a stretch.
In USA, how many hours by car do you need to find a local that doesn't speak your language?
The very same ad can easily be broadcast US-wide. Never do that in Europe (not that anyone has ever tried).
Trying to impose a law on all EU countries alone is usually unsuccessful [1]. Cultures are quite different. The feeling of being part of EU is far weaker than that of being part of your European nation. We don't say we are EU citizens. We don't watch the same thing on TV. We don't read the same newspapers. We don't have the same food habits.
My point: European countries are by far further apart than US states, and as a result, generalizations are more likely to fail.
But, sure, you do feel differently about death penalty, gun control, socialism and Mormons from state to state.
[1]: http://www.youtube.com/watch?v=loVjrNFJAikZero. The janitors and the landscapers of the company don't speak much English. The baker at the ethnic grocery down the street doesn't speak English, but his daughter does.
A lot of Europeans would answer, "I'd have to take the train (or the plane)," because they would think about the nearest country, not the nearest janitor.
I don't have to drive. Last week, I walked to a local deli and heard the following languages on the street within a few minutes: english, spanish, russian, chinese, polish(maybe, not sure) and arabic.
