Rubio doubts the peace agreement before spring 2027 US Secretary of State Marco Rubio is skeptical that Vladimir Putin will agree to any peace settlement regarding Ukraine before spring 2027, according to Svoboda Radio citing three senior European officials. Rubio also does not expect Putin to attend the G20 summit in Miami on December 14-15, despite an invitation from the Trump administration. He also believes that granting membership to Ukraine in NATO as a security guarantee is not realistic in the near term, because Moscow will never accept such conditions.
