The Munich Security Conference is set to feature a key address by US Secretary of State Marco Rubio, with much anticipation about how he will respond to the sharp criticisms made by Vice President JD Vance against European allies in the past. As the conference approaches, Rubio's comments imply a willingness to adopt a more conciliatory tone, emphasizing the importance of Europe to the United States. This shift is significant, considering the tensions that have characterized US-European relations.
