Back in 2003, there was a play in New York called "Anna in the Tropic." It played out at the "Royal Theater" with Jimmy Snits leading the cast. It went on to win a Pulitzer Prize. The play was about hope and longing. It was basically a thinly veiled production about Russia. The Anna in the play is Anna Karenina.
It was a play steeped in emotions. Within those emotions without be explicit was sexual chemistry. It was quite a play to see. But, the reason it achieved a Pulitzer is because when boiled down, was about the emotions of Russians that were either absent or never could be thought about in any social circle.
People that know something about Russian literature picked up hints of Checkov and Tolstoy. The point is that foreign influence does exist and it can be as invisible as a brilliant play that makes it to a New York stage and the acclaim of others in the way of a Pulitzer Prize.
All these cultural issues cannot be magically erased from any influence in the USA, but, Americans need to know who they are in this country and presently, Anna Karenina could possibly win an election in a Republican primary without proper documents. After all, those documents must have been sabotaged by the State Department or DOJ at the very least.
