MONS, Belgium (Reuters) -U.S. Air Force General Alexus Grynkewich took over on Friday as NATO's top military commander, sending a message of resolve and reassurance to allies concerned about potential cuts to U.S. forces in Europe by the Trump administration.
The U.S. has filled the post of Supreme Allied Commander Europe since its creation after World War Two but U.S. officials discussed ending that tradition as President Donald Trump pushes Europe to take more responsibility for its defence.
