"We see those operating on the separate tracks. One is really about the practical issue of producing this exchange. The other is a much more complex question where the Ukrainians will be in the lead and the United States will consult closely with all of our allies to support them when they are prepared to step forward and engage in that kind of diplomacy," U.S. National Security Advisor Jake Sullivan said.
