European leaders are sending a clear message against any alteration of Ukraine's borders through force, reaffirming their commitment to the principle of territorial integrity just ahead of a crucial summit between US President Donald Trump and Russian President Vladimir Putin set to take place in Alaska.

In a strongly worded statement, 26 out of 27 EU leaders declared that the people of Ukraine must have the freedom to determine their own future, emphasizing that international borders should not be changed by military aggression. The lone exception, Hungary's Prime Minister Viktor Orban, has openly maintained cordial relations with Russia and previously sought to block EU backing for Ukraine.

This unified stance highlights the growing anxiety among European nations regarding Russian actions in Ukraine, reminiscent of historical conflicts that reshaped borders amid violence. Countries in close proximity to Russia, feeling a sense of vulnerability—particularly the Baltic states, Poland, and the Nordic nations—have already taken measures such as joining NATO or increasing military readiness in response to potential threats.

Concerns have intensified within the EU about the ramifications of any US sanctions or recognition of Russian-controlled territories. Previous remarks from Trump regarding potential territorial exchanges, suggesting Russia could retain the Donbas region and Crimea in return for control of other areas, have stirred fears of changing the status quo unilaterally.

NATO chief Mark Rutte has indicated that the concept of some Ukrainian regions remaining under Russian authority cannot be officially validated, further complicating peace efforts. The EU maintains its resolve to assist Ukraine defensively while expressing its fundamental belief in the nation's sovereignty and aspirations towards EU membership.

However, the absence of Hungary from the declaration underscores fractures within the EU's unified response to the crisis. Orban criticized the message for potentially influencing international dialogue without EU participation and hinted at the need for an EU-organized summit with Russia.

As EU leaders prepare to engage with Trump on Wednesday, they aim to highlight the need for European security and the well-being of Ukraine. The anticipation builds for the leaders’ direct discussions with Russia in Alaska later this week, with the ongoing war in Ukraine hanging heavily over the agenda.
