Marco Rubio has assured European leaders the US does not plan to abandon the transatlantic alliance, saying its destiny "will always be intertwined" with the continent's, BBC reported. 

The US secretary of state told the Munich Security Conference: "We do not seek to separate, but to revitalise an old friendship and renew the greatest civilisation in human history."

He criticised European immigration, trade and climate policies, but the overall tenor of the closely-watched speech was markedly different to Vice-President JD Vance's at the same event last year, during which he scolded continental leaders, according to BBC.
