Russian President Vladimir Putin is ignoring U.S. President Donald Trump’s ultimatum to end the war in Ukraine. Despite threats of new sanctions and tariffs on Russian oil buyers, Putin remains committed to capturing Donetsk, Luhansk, Zaporizhzhia, and Kherson. Kremlin sources say Russia believes it has the upper hand and sees no reason to stop. While diplomatic talks continue, little progress has been made. Trump’s envoy is expected in Moscow, but analysts say Russia’s focus is firmly on battlefield gains over negotiations.
