Speaking after the summit, Nawrocki said NATO leaders agreed that Russia remains the alliance's primary long-term security threat because of its war against Ukraine and the broader risks it poses to Poland and Central and Eastern Europe.
"The alliance is united, strong and determined to defend its values," Nawrocki told reporters. "What Poland expected from NATO has been fulfilled."
Nawrocki also said the summit demonstrated the strength of transatlantic ties despite recent tensions, describing the United States as Poland's key strategic ally.
He said remarks by US President Donald Trump and other leaders reinforced his confidence that cooperation between Europe and the United States would remain strong.
"I leave Ankara deeply convinced that the alliance is the strongest in its history," Nawrocki said, crediting Trump's pressure on European allies to increase defence spending with helping strengthen NATO.
Asked about the future of the US military presence in Poland, Nawrocki said he was confident the number of American troops stationed in the country would not be reduced and voiced hope that the next step would be a permanent US military presence.
Nawrocki also welcomed NATO's plans to expand critical military infrastructure, including extending the alliance's fuel pipeline network farther east.
He said the existing network largely ends at the former border between East and West Germany and argued that extending it into Central Europe would strengthen NATO's eastern flank.
NATO Secretary-General Mark Rutte said on Wednesday that allies had agreed on what he described as a historic EUR 27 billion investment project to modernise the alliance's fuel storage and distribution network, including new pipelines extending to eastern member states.
