The United States, Britain, France, and Germany back Rutte to succeed Jens Stoltenberg, who will step down as NATO’s head in October.
Additionally, Dutch media reported on Tuesday that Hungary has also dropped its opposition to Rutte. Turkey informed its allies in April that it would support Rutte as well.
NATO decisions require consensus, meaning any candidate needs the support of all 32 allies. With endorsements from Slovakia and Hungary, Rutte now only awaits support from Romania.
Romanian President Klaus Iohannis stated in March that he was running for the NATO top job, emphasizing the need for better representation of Eastern European states in Euro-Atlantic leadership roles.
