Writing on X from his personal account on Friday, Rose said Tusk had asked "a very serious and thoughtful question" that deserved "a serious and respectful answer."
"Yes, America is loyal to its allies — but we too ask if our allies are as loyal to us as they expect us to be to them," he wrote.
Rose cited decades of American commitment to European security: more than USD 13 trillion spent on Europe's defence since World War II, over 100,000 US troops currently stationed across the continent, including 9,000 in Poland, and more than USD 100 billion earmarked for European defence this year.
He described President Donald Trump's commitment to Poland as "iron clad and rock solid," adding that no country had proven a stronger American ally since the end of the Cold War.
Speaking to journalists shortly afterwards, Tusk said the exchange illustrated precisely the concern he had chosen to raise publicly – one that had made "quite an impression" among European leaders.
He said he had "absolutely no reason to doubt the sincerity" of allies' intentions under Article 5, but added that practical decisions were needed to ensure Poland could be helped quickly if the situation demanded it.
In his earlier interview with the Financial Times, Tusk questioned whether the United States would honour its NATO defence commitments and warned that Russia could attack a NATO member within "months rather than years." He asked whether the alliance remained politically and logistically ready to respond.
He also called for the EU to strengthen its own mutual assistance clause under Article 42(7) of the EU Treaty.
