Donald Trump has read out a letter from Volodymyr Zelenskyy saying Ukraine is ready to negotiate and the president says he's getting strong signals from Russia that it is also ready for peace, but - if that deal boils down to Ukraine surrendering territory, American mining companies extracting minerals from Ukraine, and no security guarantee - is that real peace? And would a deal like that hold?

In this new world of strong man politics, has Ukraine been bullied and Russia indulged? And what does all this tell us about Trump's new world order? 

In this episode of the Fourcast, Krishnan Guru-Murthy is joined by the American historian and writer Professor Timothy Snyder, who's an expert on Ukraine, Russia and eastern Europe, having written highly acclaimed books on tyranny and freedom.
