How might US-Russia talks impact Europe's influence in Ukraine?

The recent US-Russia discussions on Ukraine held in Saudi Arabia appear to be marginalizing European stakeholders. According to the news commentator, Washington's approach of sidelining Europe in these talks could reveal the limited actual influence that European nations have in matters concerning Ukraine. This diplomatic dynamic suggests a power shift where major decisions about Ukraine's future may increasingly be determined by direct US-Russia negotiations rather than through a more inclusive process involving European partners, despite Europe's geographic proximity and strategic interests in the region.
