The US is an outlier, though, New York even more so. More than any city in the US, NYC can claim to be the epicenter and cradle of the kind of mythical nation-history-building to which every nation-culture's opportunistic immigration and subsequent assimilation has contributed to and adopted as their own.
The very notion of the American dream is codified on New York's main landmark: "give me your poor huddled masses" etc. The story of America is necessarily the story of many populations coming together to create something new. The Irish may have the old country to look back on, for example, but their original cultural heritage has been superseded by that of America itself.
Russia has no such story; along with its disparate satellites (Ukraine, Belarus and so on) it has a long history of single peoples mostly staying still, or emigrating. The idea of a "Russian people" with a common cultural heritage has been a fairly constant concept for hundreds of years, whereas "the American people" is a very new one, historically.
