Guest: Michelle Shephard, a journalist, author and filmmaker who was the Star's national security reporter for nearly 20 years

Everyone who is old enough has some kind of memory of where they were and what they were doing on September 11, 2001, when the two towers of the World Trade Centre in New York were brought down by commercial planes hijacked by members of the terrorist organisation Al-Qaeda. Almost 3,000 people lost their lives.

9/11 led to two decades of wars, including the U.S. in Afghanistan and Iraq, hundreds of thousands of dead, a complete shift in border and security laws, personal freedoms – and implications for Muslims that continue today. With the U.S. withdrawal from Afghanistan, leaving the same Taliban back in power that the war was meant to topple, many are questioning the last twenty years since 9/11 and what it all meant.

Michelle Shephard, a journalist, author and filmmaker who was the Star's national security reporter for nearly 20 years joins me as we talk about where we were then, where we went and how we ended up here.
