Russian leader’s antagonism to Zelenskyy and lack of interest in a ceasefire leaves colossal task for US

• David Lammy: Trump’s right, Putin can take the hard or easy way

On paper, everyone is in agreement: Donald Trump says he wants a ­ceasefire; Kyiv’s ­negotiating team has already agreed to a 30-day ceasefire ­proposal at marathon talks with the Americans in Jeddah; and Vladimir Putin says he accepts the idea, albeit with a few “nuances”.

But Putin’s so-called nuances are bigger than mere wrinkles, and at the end of an intense week of diplomacy around Russia’s war in Ukraine, a ceasefire – never mind a sustainable peace – still looks to be something of a distant prospect.
