What was the purpose of President Trump's envoy's visit to Kyiv and what tensions emerged from recent peace talks?

President Trump's envoy Keith Kellogg visited Kyiv to meet with President Zelensky about the ongoing Russia-Ukraine war and security guarantees. The visit occurred amid tensions following US-Russia peace discussions in Saudi Arabia that notably excluded Ukraine, which surprised President Zelensky who firmly stated that decisions about ending the war cannot be made without Ukraine's participation. The situation was further complicated by President Trump's disappointing reaction to Zelensky's concerns, with Trump apparently blaming Ukraine for the war's continuation despite Russia being the invading force. This diplomatic tension highlights the complex geopolitical challenges Ukraine faces as it seeks to maintain its voice in peace negotiations while securing necessary security guarantees.
