Why Turkey is invading Northern Syria

On the afternoon of October 6, US President Donald Trump and Turkish President Recep Tayyip Erdogan discussed the more than 8 year Syrian civil war. That one phone call upended nearly five years of US policy in Syria. Shortly afterwards, the White House released a statement announcing their withdrawal from the country and Erdogan's plans to launch an offensive across the Northern border.  Host James Haines-Young looks at why Donald Trump stood aside for a Turkish invasion of Syria and why does Ankara want a new war.
