President Trump wants illegitimate Venezuelan President Nicolas Maduro out. Given the economic collapse, chaos, and scam elections that his socialist government has presided over, that’s a great goal. But with a showdown set for Saturday, Trump has backed himself into a corner should his show of force not quite work out as intended.

On Monday, Trump threatened that the Venezuelan military “would lose everything” if it continued to support illegitimate President Maduro. On Thursday, Maduro made clear that his regime wasn’t going to back down and announced that the border with Brazil would be closed Thursday night, and is considering also shutting down the border with Colombia.
