European leaders have warned Ukraine not to accept concessions to Russia without security guarantees from the USA.

The Wall Street Journal reported that European leaders issued a stern warning to Ukrainian President Volodymyr Zelensky, urging him not to make concessions to Russia without solid security guarantees from the United States. During a phone call on December 1, Zelensky spoke with European leaders, including French President Emmanuel Macron and German Chancellor Friedrich Merz, who emphasized the importance of U.S. involvement in providing these guarantees. There is growing concern in Europe about the lack of clarity from Washington regarding its response in the event of a breach of a potential peace agreement by Russia. These warnings reflect European efforts to influence the peace negotiations, which are largely led by the U.S., without significant European involvement.
