European leaders are set to gather for an emergency summit on the war in Ukraine amid growing concerns over US President Donald Trump’s interventions in the peace process. The summit, called by French President Emmanuel Macron, will be attended by UK Prime Minister Sir Keir Starmer, who said it was a “once-in-a-generation moment for our national security” and that Europe must take a greater role in NATO.

Sir Keir stated, “This is a once-in-a-generation moment for our national security where we engage with the reality of the world today and the threat we face from Russia.” He added, “It’s clear Europe must take on a greater role in NATO as we work with the United States to secure Ukraine’s future and face down the threat we face from Russia.”

Polish Foreign Minister Radoslaw Sikorski said, “President Trump has a method of operating, which the Russians call reconnaissance through battle. You push and you see what happens, and then you change your position, legitimate tactics. And we need to respond.”

Ukrainian President Volodymyr Zelensky has called for the creation of an “army of Europe” amid concerns that the US may no longer come to the continent’s aid. Zelensky said, “Yesterday, here in Munich, the US Vice-President made it clear that the old relationship between Europe and America is ending, and Europe needs to adjust to that.”

The emergency summit comes after Trump’s special envoy to Ukraine, Keith Kellogg, said European leaders would be consulted but not take part in any talks between the US and Russia over ending the war in Ukraine.
