"RUSSIA: TRYING TO PUT THE OBAMA ADMINISTRATION ON THE DEFENSIVE"
Obama might be "the new JFK" (http://www.slate.com/id/2164662/) (http://www.telegraph.co.uk/news/worldnews/1565992/Barack-Obama-is-JFK-heir,-says-Kennedy-aide.html) but that is not necessarily all good.
Khruschev thought JFK was young and inexperienced; Obama has even less experience.
This is not necessarily a weakness of Obama (in fact, some liked the idea of a president who is not a Beltway insider), however it can lead to dangerous situations.
Obama might be a lot of things, but he is not likely to take Russian pushing idly. Foreign leaders might be tempted to play a dangerous game of chicken with our young president. That is how wars happen.
