In recent weeks, Trump has criticised his military allies for not spending the 2% of GDP on defence called for in Nato guidelines.

Heading into the conference, Bettel tweeted the Luxmebourg planned “to increase its defence expenditure and move towards the 2% guideline within a decade”.

During the summit, Trump called on Nato members to double their defence spending, from 2% to 4% of GDP.
