The Pyramid at the End of the World (TV story)

 was the seventh episode of the tenth series of Doctor Who produced by BBC Wales.

Synopsis
At a war zone in Turmezistan where American, Chinese, and Russian armies are about to meet, a 5,000 year old pyramid stands. It's very strange, but one thing raises the suspicions of the Twelfth Doctor: it just appeared overnight. The aliens inside claim that humanity would die by their own hand. Soon, the Doctor, Bill and Nardole are facing an invasion the likes of which they have never seen before. Before they invade, the aliens need the permission of humanity.

Story notes

 * This is the longest title for a Doctor Who episode, with eight words
 * A line of dialogue referring to terrorism was reportedly excised from the episode, out of respect for the victims of the, which occurred five days prior to broadcast.
 * When the Secretary General asks about the President, Bill says she doesn't know him, and says he is "orange". While never stated in the narrative, this is a reference to Donald Trump. This would therefore suggest that the President in Extremis is a representation of Trump.
