As we've been reporting, the US and Ukraine signed a natural resources deal yesterday after months of negotiations.
A former US ambassador to Ukraine tells BBC Radio 4's Today programme that this came after a turning point—when Trump and Zelensky spoke at the Vatican during the Pope’s funeral.
William B Taylor says that after speaking directly to Zelensky, Trump began to doubt that President Putin is a reliable partner. As a result, for Trump, this deal, which "started out as pretty lopsided", has now become a "balanced mutually beneficial agreement", according to Taylor.
While there’s no explicit military security guarantee in the document, Taylor says the provision for long-term investment in Ukraine is “an indication of seriousness” from the Americans.
