Ukraine’s continued focus on Kursk shows how important Kyiv believes it is to hold on to Russian land, especially if Trump pushes both sides to the negotiating table.

President-elect Trump said late Thursday that a meeting is in the works with Russian President Vladimir Putin to discuss ending the Kremlin's invasion of Ukraine. Why it matters: Trump said on the campaign trail that he would swiftly end the nearly three-year-old war in Ukraine within 24 hours of taking office.

Ahead of Trump's inauguration on January 20, the President-elect has said he is planning a meeting with Russia's leader, which the Kremlin has denied.
