Summarizing Donald Trump's worldview isn't easy, but this may come close: The world is a violent place, and it demands a violent response, according to NBC News' analysis.
He's made news by giving out a Republican rival's phone number, tweeting about a "sex tape" and even accusing his opponent, Hillary Clinton, of possibly taking drugs.
Trump's emphasis on violence and retaliation, especially outside the confines of the law, is unique among modern nominees and is rooted in a set of guiding principles. In his eyes, the world is an unforgiving place where cities are "war zones," where "rapists" are streaming across the border and where jealous rivals are hatching plots to humiliate America and Trump personally. To prevail in such an environment, he suggests, the response to any slight must be swift and overwhelming. Dwelling on limits imposed by law or tradition is usually a secondary concern.
The Trump campaign did not respond to requests for comment for this story. With Trump's language heating up in the final days and his list of enemies growing fast, some civil rights groups and law enforcement officials are raising fears that things could get out of hand.
