The presidents of Russia and the US are both down as “maybes” for attending the peace talk with Ukraine, due to start later today. 

Ukraine's Volodymyr Zelenskyy is personally attending the talks in Turkey and the Kremlin's sending a delegation – it remains unclear whether it'll include Vladimir Putin. 

Donald Trump says he might turn up if the circumstances are right.  

Former Foreign Minister Sir Don McKinnon told Mike Hosking Trump's involvement in the talks could be a bad thing. 

He says he'd be prepared to give too much away, which undermines what liberal democracies like New Zealand believe in.
