Earlier that day, Ukrainian President Volodymyr Zelenskiy pushed for the establishment of a European army, arguing that Europe can no longer rely solely on U.S. protection and needs a strong military to earn respect from Washington.
When asked about the idea of a European army, Sikorski cautioned against the term, noting that it can mean different things to different people.
"If you understand by it the unification of national armies, it will not happen," he said. "But I have been an advocate for Europe, for the European Union, to develop its own defence capabilities."
He mentioned that the EU is in the process of forming a strengthened brigade.
"If the U.S. wants us to step up in defence, it should have a national component, a NATO component, but I also believe a European EU component, EU subsidies for the defence industry to build up our capacity to produce, but also an EU force worthy of its name," Sikorski added.
He also emphasized that deploying Polish troops in Ukraine is "not an option," as Poland's NATO commitment is to safeguard its own territory on the eastern flank.
