The collapse of the Soviet Union at the end of 1991 appeared to usher in a remarkable new era of peace and co-operation with the West. This, we were told, was the end of history: now the entire world would embrace enlightenment values and liberal democracy.
Reality has proved very different. Russia emerged from the 1990s battered and humiliated, a latter-day Weimar Germany - its protests ignored as NATO expanded eastwards to take in Moscow's former satellites. Vladimir Putin offered a new start when he took the place of the erratic Boris Yeltsin in the Kremlin, but, determined to restore his country's bruised pride, he has wrong-footed the West with his incursions into Georgia, Ukraine and Syria. A cold war threatens to turn hot once again.
In this talk which is based on exclusive interviews with key players either side of the new divide,  Conradi addresses how we can get relations back on track before it's too late.
Peter Conradi is the Foreign Editor of The Sunday Times. During his time as Foreign Correspondent in Moscow, he witnessed the USSR's collapse first-hand. His previous books include The King's Speech, which inspired the Oscar-winning film.
A Q & A session will follow.
