European allies are concerned about a potential US withdrawal of support for Ukraine, viewing it as a threat to European security and the principle of unchanging post-WWII borders. They believe that a US pullout would embolden Russia and undermine the international order.
President Trump's administration presented proposals to Europe and Ukraine that were viewed as too favorable to Russia by European officials. This created a dilemma for European leaders, who are considering continued support for Ukraine even if the US withdraws.
Despite Trump's stance and the ongoing war, European countries, particularly Poland, have expressed their determination to continue supporting Ukraine. They highlight the importance of upholding the principle of maintaining post-WWII borders.
Following a deadly attack on Kyiv, President Trump publicly urged Vladimir Putin to stop the violence, demonstrating his frustration with the lack of progress towards ending the war. However, little hope is held that Putin will cease hostilities.
