Fox News: Ukraine’s battlefield reshaping NATO’s future
Ukraine’s battlefield experience is increasingly being viewed across NATO’s eastern flank as a defining force in reshaping the alliance’s future, as Russia’s war on Ukraine enters its fourth year. Officials say the conflict has accelerated changes in doctrine, procurement and strategy across Europe.
In Lviv, Mayor Andriy Sadovyi said Ukraine’s armed forces have become central to European security debates.
"I think today the Ukrainian army is the number one army in Europe," he told Fox News Digital.
"I think NATO needs the Ukrainian army," he added.
NATO Secretary-General Mark Rutte has confirmed that Ukrainian President Volodymyr Zelenskyy has been invited to the alliance’s July summit in Ankara, underscoring Kyiv’s growing strategic relevance despite not being a member of NATO.
US Secretary of State Marco Rubio has described the upcoming gathering as pivotal, warning of structural weaknesses in allied defence production. He called it "one of the more important leaders’ summits in the history of NATO."

Retired US Lt Gen Richard Newton said the conflict is already reshaping Western defence planning.
"A number of nations are taking a page out of Ukraine’s transformation of its defense industrial base, in terms of quality as well as the tremendous increase in quantity of arms to the frontlines as well," he said, adding, "The Pentagon is taking note and working to encourage the transformation of our own industrial base so we can drastically improve and more rapidly provide capabilities to our forces in the field, not in a matter of years but in months and perhaps even in weeks."
Polish Foreign Minister Radosław Sikorski welcomed continued US force posture in Europe, saying:
"I want to thank President Trump for his announcement that the presence of American troops in Poland will be maintained more or less at previous levels," Sikorski said.
Polish Deputy Defence Minister Paweł Zalewski said Ukraine has become a reference point for modern warfare doctrine.
"There is not a military in the world which is better than Ukraine" in understanding today’s battlefield realities, he said.
Retired NATO Supreme Allied Commander Europe Gen Philip Breedlove said the war has fundamentally altered global military thinking.
"The war in Ukraine has changed far more than just NATO’s understanding of modern warfare — it has changed the whole world’s understanding," he said.
Analysts say the war has accelerated NATO expansion, with Finland and Sweden joining the alliance after Russia’s invasion, and intensified debate over Europe’s role in collective defence. NATO members along the eastern flank argue the conflict has effectively made Ukraine a de facto laboratory for modern warfare, shaping the alliance’s future posture.
