Joe Biden to use Nato summit to atone for damage of Trump years

Omens are favourable, but experts warn previous four years will have lasting consequences

Three years ago it was Donald Trump who stunned Nato members at a summit in Brussels, warning that he may be prepared to pull the US out of the western military alliance if its other members did not increase their defence spending.

At a summit in the same city on Monday, it falls to Joe Biden to repair the damage from four years of his predecessor's freewheeling theatrics, although experts caution that the Trump era will have lasting consequences.
