BRUSSELS — One of Europe’s most senior politicians recounted how former U.S. President Donald Trump privately warned that America would not come to the EU’s aid if it was attacked militarily.

“You need to understand that if Europe is under attack we will never come to help you and to support you,” Trump told European Commission President Ursula von der Leyen in 2020, according to French European Commissioner Thierry Breton, who was also present at a meeting at the World Economic Forum in Davos.
