There are not enough people who remember this but I'm glad Rubio does -- in the heat of trying to praise President Buzzfeed as much as possible, Biden actually said that he counseled him against pulling the trigged on the Bin Laden operation. And he said it was supposedly the "courage" of Obama that made him do it anyway. SO that means that if Biden was president, Osama Bin Laden would still be alive!! It's devastating critique that Rubio is smart to employ.
I believe it was a 'kill or capture' mission. Had it simply been a kill mission, a drone or missile, or some other local method would have sufficed. Were Joe's concerns centered around the obvious theatrical nature of the operation. We may never know, but I doubt it had anything to do with courage.
