U.S.-Ukraine dispute overshadows European defense summit

A diplomatic dispute between the U.S. and Ukraine has overshadowed a European summit in London focused on Ukraine's defense. President Trump criticized Ukrainian President Zelenskyy for perceived ingratitude, raising concerns among European leaders about support for Ukraine. The summit, hosted by British Prime Minister Keir Starmer, aims to strengthen European unity and support for Ukraine amid shifting U.S. positions. Leaders from over a dozen countries will discuss strategies to ensure Ukraine's sovereignty and security. European leaders are now under pressure to increase military spending and take a more active role in supporting Ukraine. The recent tensions have prompted calls for unity and a reassessment of defense strategies across Europe.
