The war in Ukraine and the existential threat that Russia poses to European security has topped NATO’s agenda in each of its summits since 2022.

Ukraine has been invited to attend the NATO summit in The Hague later in June, according to NATO Secretary General Mark Rutte, who added that further details on participants and program would be published soon.

Officials organising a NATO summit in The Hague this month are expected to keep it short, restrict discussion of Ukraine, and choreograph meetings so that Volodymyr Zelenskiy can somehow be in town without provoking Donald Trump.

John Healey, the British defence secretary, said the NATO ally is "stepping up its support for Ukraine" with a £4.5-billion ($6.1-billion) package of military aid in 2025, and that the U.K. has completed a delivery of 140,000 artillery munitions since the start of the year.

A Ukrainian drone attack last weekend likely damaged around 10% of Russia's strategic bomber fleet and hit some of the aircraft as they were being prepared for strikes on Ukraine, a senior German military official said.
