What were President Trump's controversial remarks about Ukraine's leadership?

President Trump made disparaging remarks about Ukrainian President Zelensky, stating that he should have ended the war himself "a long time ago." This statement was particularly controversial because it placed blame on Ukraine's leadership despite the fact that Ukraine was invaded unprovoked by Russia. The president's comments seemed to shift responsibility to the victim of the conflict rather than acknowledging Russia's role as the aggressor. These remarks have significant implications for US-Russia relations and potential peace negotiations, raising questions about the US position on the conflict.
