Donald Trump expressed deep skepticism about a proposed European summit on Ukraine and a US peace plan, engaging in "strong words" with European leaders including Emmanuel Macron, Keir Starmer, and Friedrich Merz.This stance, coupled with a US National Security Strategy critiquing the EU's challenges, widened the rift between the United States and Europe, despite EU diplomatic efforts involving Ursula von der Leyen, Antonio Costa, and Aleksandar Vučić.The discord persisted after a
London meeting of European leaders with
Volodymyr Zelensky, and Trump later described Europe as a bloc in "decadence," while the
European Commission also fined
X €120 million.
