For three days in November, 1943, Churchill, Roosevelt, and Stalin met in Tehran, Iran and made decisions that would change the course of World War II.  It's the subject of a new book by Fox News' Bret Baier titled Three Days at the Brink: FDR's Daring Gamble to Win World War II, and today Bret Baier shares how his latest book fits into his Three Days in History trilogy, why the Tehran Conference was so crucial to Allied victory, and how it also set the stage for the Cold War.  He reveals why Stalin held all the cards going into Tehran, how FDR managed to use Stalin's eavesdropping to his advantage,  and why Roosevelt had to risk hurting Churchill’s feelings in order to make a deal.  He also discusses how lots and lots of alcohol greased the wheels of diplomacy among the three leaders, similarities between the personal diplomacy styles of FDR and President Donald Trump, and some key leadership lessons from those three days in Tehran.  Plus this beltway insider weighs in on the mood in Washington as Congress moves forward with Impeachment.
