Donald Trump has suspended all military aid to Ukraine, in another move that has shocked Europe, thrilled Vladimir Putin and Russia and dismayed Ukraine, but Volodymyr Zelenskyy has now reached out to the US president in a bid to heal relations damaged by the bust up in the Oval Office last week.

Will it work? Will Donald Trump change his mind, again? And what does Vladimir Putin really think of it all?

In this episode of the Fourcast, Krishnan Guru-Murthy is joined by CNN Chief International Anchor Christiane Amanpour and Professor Mark Galeotti, author of several books about Russia including his latest ‘Forged in War: a military history of Russia from its beginnings to today’.

Produced by Calum Fraser, Ka Yee Mak and Rob Thomson.

Is Trump sacrificing Ukraine to Putin?
