Russian Foreign Ministry did not pass American censorship

Russian Foreign Minister Sergey V. Lavrov did not manage to publish his article in the leading American journal The Foreign Affairs. The article was designed to be a response to a one of former Ukrainian Prime Minister Yulia Tymoshenko, that had been published in May -- entitled "Containing Russia." After negotiations with the magazine Sergey V. Lavrov has pulled his article “because of the censorship.”

“The Editors, with reference to their own standards, substantially edited the article, if not censored it. It was cut by 40%, losing a considerable part of its original meaning. Some editing even meant that Sergey Lavrov was to subscribe to certain Foreign Policy positions of the present US Administration, to which Russia objects on grounds of principle.” - it is said in the statement of the Foreign Ministry.

American, land of the free and of free expression? Don't bet on it these days.
What the devil was "Foreign Affairs" so afraid of in this article that they wouldn't publish it in its original form?
