enemy -> attention (this is why Russia craving for yesterday level attention today is so hard trying to pose as an enemy). Also add that 20th century had a lot of immigrants from Russian Empire territories (Jews before WWI, Russian aristocracy and just educated people running from Revolution, Jews and dissidents after the WWII). And USSR with its communism looked like something ahead, a next stage in progress forward.

That all has changed. Today in US it is absolutely not interesting to study the self-reflections of people with too much time on their hands in a society without opportunities and without good access to mental health professionals - ie. Russian literature (as well as literature of almost any other culture - because they pretty much all deep in the past and the issues they explore in many cases has already been answered). US has moved past that. People like Musk illustrate it - work, make money, improve and expand civilization. This is why the only good writers in Russia since the space flights started have been Strugatskies brothers - who explore the issues of such civilization expansion and Pelevin - who explores absence of such expansion and the resulting end-game of the above mentioned "self-reflection", ie. he finishes what Dostoevsky/Chehov started.
