Can trust be built between Turkey and Armenia?

Armenia and Turkey have often been described as enemies. Their longest dispute is over what to call the mass killings of Armenians during WWI. Armenia calls it a genocide, but Turkey disagrees. Both sides are now trying to normalise ties, but why is this happening? And can they build trust after decades of animosity? Join host Imran Khan.  With guests: Mitat Celikpala - Professor of İnternational Relations at Kadir Has University. Richard Giragosian - Director of the Regional Studies Center in Armenia. Matthew Bryza - Non-resident senior fellow at the Atlantic Council's Eurasia Center.
