Here's the difference between Biden and Ryan: whereas Biden has been studying foreign policy for many decades (over which he's made his share of mistakes), everything Ryan knows about foreign policy, or at least everything he's shown us he knows, comes from interventionist ideologues with talking points that test well among the base and bear little resemblance to reality. I didn't quite realize how awful Ryan's performance was until I read the transcript of the debate. Biden did smile too much. It distracted me from Ryan's apparent unfitness to be commander-in-chief.
