Key metric: International Relations and Diplomacy

As a social scientist, I analyze that this article highlights a significant shift in diplomatic approach towards the Russia-Ukraine conflict. Trump's meetings with European leaders and Zelenskyy demonstrate an attempt to broker peace without a ceasefire, which is unconventional. The united European front and Trump's emphasis on Europe taking more responsibility for Ukraine's security indicate a potential realignment of international roles in the conflict. The article suggests a move towards more direct negotiations between conflicting parties, with the U.S. playing a facilitating role. This approach could significantly impact the trajectory of the conflict and reshape international diplomatic norms in conflict resolution.
