In the early hours of Saturday morning, Australian time, Donald Trump and Vladimir Putin will sit down for a one-on-one meeting in Alaska, talks the US President hopes will lead to a ceasefire in Ukraine. The Russian leader has praised what he called ‘sincere efforts’ by the US to end the war… and floated the prospect of a nuclear arms deal. Kyiv and its European allies have urged Trump not to make any deals that carve up Ukrainian territory and put the continent’s long-term security at risk.
