Once again Trump brought his wrecking ball to the Nato summit, and once again the alliance survived. But for how long? | Paul Taylor

As the US president swung between threats to take Greenland and promises of help for Ukraine, pledges of a stronger Nato' were lost in the wind

Nato leaders survived another nerve-racking summit with Donald Trump and the 77-year-old defence alliance lives to fight another day, proving its durability against Atlantic storms. But it will never feel safe as long as the unpredictable, vengeful and ruthlessly transactional US president is in the White House.

As usual, Trump stole all the headlines at the annual summit, with a mixture of Nato-bashing and implausible threats to take control of Greenland and cut trade with Spain. He declared the ceasefire with Iran dead and called Iranian leaders scum" as US warplanes bombed Iranian targets along the strait of Hormuz. Pitted against such irresistible clickbait, no Nato communique stood a chance of public attention.
