Honestly, I think Biden's intent was to try and draw a parallel between Obama and JFK and state that Obama could handle a crisis new in his presidency just like JFK did. The problem is that somewhere between his brain where the idea originated and his mouth where it finally saw daylight the "Biden Factor" came into affect.
I think Biden's attempts to pat himself on the back for all of his foreign policy "expertise" while concurrently trying to paint Obama as JFK reborn collided and "that" speech came out.
As a student of human psychology politician's never cease to fascinate me. All through the primary Biden hammered at Obama for his lack of experience and if I'm not mistaken called him naive more than once. Now he hails him as the second coming. Which Joe Biden (if either) is the real person and whom should we believe?
