The United States has cast itself in the vital role of go-between, or mediator, in the latest push to end the Ukraine war. By facilitating communication and allegedly securing agreements between two leaders who are otherwise at war, the U.S. is performing a classic function of international diplomacy.
As a go-between, the Trump administration is able to absorb some of the political risk for both sides. Putin and Zelenskyy can explore the possibility of a meeting through the American channel without having to make direct, public overtures to each other, which could be seen as a sign of weakness at home.
The mediator role also allows the U.S. to shape the agenda and the terms of engagement. By proposing the structure—a bilateral meeting on territory, with the possibility of a trilateral follow-up—the U.S. is not just passing messages but actively designing the architecture of the peace process.
However, being an effective go-between requires being seen as credible by both sides. While the U.S. is a firm ally of Ukraine, President Trump has also cultivated a direct relationship with President Putin. His ability to leverage this unique position will determine his effectiveness as the central mediator in this high-stakes effort.
