What is President Trump's controversial claim about the Ukraine war?

President Trump claims that Ukraine 'could have made a deal' to end the conflict, suggesting the war could have been avoided through negotiation. This statement echoes Russian perspectives and has generated significant bipartisan backlash from experts concerned about U.S. foreign policy direction. The claim is controversial because it appears to place responsibility on Ukraine rather than acknowledging Russia's invasion of a sovereign nation. Experts worry such rhetoric undermines America's allies and could have long-term negative effects on Ukraine's defense against invasion, while potentially spreading misinformation about the conflict's origins.
