Despite President Trump’s stalled efforts to broker peace and Russia’s planned summer offensive, analysis by Michael Kimmage (Kennan Institute) suggests the military tide in Ukraine may be turning against Moscow.

An exchange of prisoners of war (POWs) between Ukraine and Russia taking place on May 23 is still ongoing, a source familiar with the exchange told the Kyiv Independent, after U.S. President Donald Trump said the swap had been "completed.

The U.S. president says the onus is on Russia and Ukraine, not Washington, to end the war, according to a report.

CHERNIHIV REGION, Ukraine (AP) — An exchange of prisoners between Russia and Ukraine from their more than three-year war was underway Friday, a senior Ukrainian official said. The swap was not yet finished, according to the official, who spoke on condition of anonymity because he was not authorized to speak publicly.

President Donald Trump said on Friday that a major prisoner swap was just completed between Russia and Ukraine.

Few details were known about Monday's call, aside from Trump's reported attempt to initiate peace talks aimed at ending the ongoing conflict in Ukraine.
