Trump's Worldview as Commander-in-Chief

Guest: Thomas M. Nichols, PhD, University Professor, National Security Affairs, U.S. Naval War College In his prime time speech to the nation Tuesday night, President Donald Trump said Americans are in grave danger from people and drugs sneaking over the US-Mexico border and only a wall can protect us. Trump’s depiction of the situation as a crisis is questionable, since US Customs and Border Protection says the number of people apprehended at the border has been declining for more than a decade. Plus, nearly all of the heroin that comes into the US from Mexico arrives with people legally crossing at ports of entry, which a wall would not fix.
