This week, following unsuccessful attempts by Volodymyr Zelensky to repair the damage done during last week's Oval Office row, Donald Trump cut all American military aid to Ukraine. It was a huge move that made clear once and for all that Zelensky is no longer in favour in Washington. 

The decision divided America, provoked widespread criticism in Europe, and was heartily cheered by Russia. So what has led to this? Trump's apparent dislike for Zelensky has not come out of nowhere, nor has his embrace of Vladimir Putin's view of the war in Ukraine and NATO.

There is a long and hugely contested history that's crucial to understanding the events of the last few weeks, and whatever will unfold in the coming months and years of Trump's presidency. On today's episode Venetia Rainey speaks with Orysia Lutsevych from Chatham House about the history of Trump's relationship with Zelensky, from Hunter Biden to the mysterious server, and Roland Oliphant looks at Trump's embrace of Putin, from KGB asset rumours to the Mueller investigation.
