At the America Business Forum in Miami, Donald Trump delivered what could best be described as a geopolitical roast with a side of campaign rehearsal. Between warning that New York has gone “full communist,” declaring South Africa unfit for the G20, and teasing a mysterious “settlement” with Harvard, Trump’s speech ping-ponged between policy, punchline, and performance art.

He praised Miami as the last bastion of capitalism, suggested refugees may soon be fleeing from Manhattan, and reminisced about the good old days when America only had “socialists” to worry about. Somewhere between the Harvard hair jokes and the G20 travel boycott, the line between stump speech and stand-up blurred completely.

In short: a business forum became a Trump rally became a meme in real time.
