Belgium's newly appointed defence minister, Theo Francken, has taken an unconventional approach in his latest diplomatic spat against Russia.
Francken took to Instagram, posting Selena Gomez's song 'Calm Down' in response to a nuclear threat from Russia's former president Dmitry Medvedev. While tensions between NATO and Russia have been high for years, few expected a sitting minister to address a nuclear threat using American pop music.
