The US president could embrace the role of peacemaker, or become the patsy who restored Russia’s imperial standing

The past few weeks have seen a flurry of activity billed as progress in the Russia-Ukraine peace process. Yet for Ukrainians, the reality remains unchanged: airstrikes still thunder across their cities, homes still burn, lives are still lost. Against this grim backdrop, the Russian leader, Vladimir Putin, has seemed more than content to bask in the literal red-carpet treatment afforded by the president of the United States.

Donald Trump, who has anointed himself mediator of this war, has nearly exhausted the lexicon of contradiction. Some days he proclaims that he alone can end this war. Then he insists that peace talks should be left to the two parties. At times he boasts that Putin “respects” him; at others, he castigates Putin for “going absolutely crazy”. This month, Trump vacillated between putting US troops on the table and ruling it out. Now he is reportedly considering using US private military firms for the job.
