When revolutions happen, everything changes. In this episode, we'll look at why one revolution was launched when a rebel leader in southeast Asia started climbing trees; how Teddy Roosevelt's son led a CIA-backed coup in 1953 that contributed to the Iranian revolution; and why one East German guard had a bad day -- and forever changed history as a result.   ----   Power Corrupts is written and narrated by Brian Klaas. The executive producer and sound editor is George McDonagh.
