Former U.S. national security adviser John Bolton renewed sharp criticism Sunday of the 28-point peace proposal advanced by Donald Trump to end the war between Russia and Ukraine, calling the reasoning behind it a "mystery" and the approach "incoherent.

From the front-line city of Pokrovsk in eastern Donetsk, to Zaporizhzhia in the south, there is little doubt that Russia is making advances. But, battlefield monitors suggest the picture is not quite so bleak for Ukraine as Trump and Putin suggest.

In a Truth Social post on Sunday Trump declined to blame Russia for the conflict in Ukraine, instead targeting his rage at Kyiv and US allies in Europe for failing to reach a truce. “UKRAINE ‘LEADERSHIP’ HAS EXPRESSED ZERO GRATITUDE FOR OUR EFFORTS AND EUROPE CONTINUES TO BUY OIL FROM RUSSIA,” Trump said.
