He was a key global leader and stood by America’s side in one of its darkest hours. Former British prime minister Tony Blair joins Washington Post Live to discuss the terrorist attacks of Sept. 11, 2001, how extremism has evolved and where the world stands today in its war against terrorism. Blair also explains his concern that the West may have lost its will to exert its traditional leadership role and why he calls the withdrawal from Afghanistan “tragic, dangerous and unnecessary.”
