"The presidency's most crucial duty is the protection of American national security. Yet, interviewed by Hugh Hewitt months into his campaign, Donald Trump did not know the key leaders of the global jihad. The man who would be commander-in-chief was unfamiliar with Hassan Nasrallah, the Hezbollah leader who has been murdering Americans for over 30 years; Ayman al-Zawahiri, Osama bin Laden's longtime deputy who has quite notoriously commanded al-Qaeda since the network's leader was killed by U.S. forces in 2011; and Abu Bakr al-Baghdadi self-proclaimed caliph of the Islamic State (ISIS) and a jihadist so globally notorious that many teenagers are aware of him. Of course a man who wants to be president should make it his business to know such things."
