In a Trumpian world, the UK and the EU need to agree on greater commitments to collective security

European leaders, including Theresa May, should take Donald Trump’s blatant opportunism at face value. The self-professed “dealmaker” appears intent on striking new international partnerships and stoking latent animosities in an effort to shake up the international order. His aim: stacking the cards more “fairly” for the United States. Paul Angelo argues that if Europe is to figure prominently in Mr Trump’s calculations, Brussels and London will have to make the Republican administration an offer it can’t refuse—one that entails greater commitments to collective security and a resounding defence of the international liberal order.
