Following an unprecedented verbal spat between former U.S. President Donald Trump and Ukrainian President Volodymyr Zelensky, concerns are mounting over NATO’s stability and Europe’s security. Analysts believe Trump’s efforts to strengthen ties with Russian President Vladimir Putin have heightened tensions. BBC journalist Jeremy Bowen suggests that this rift signals a deepening crisis between the U.S. and NATO’s European members. Trump stated that Zelensky should return for negotiations only if he is ready for peace. Speculation is growing that Washington may reduce military aid to Ukraine following the dispute.
