The United States warned that a Russian drone (unmanned aerial vehicle) violating the airspace of Poland, a member of the North Atlantic Treaty Organization (NATO), was "an unacceptable and dangerous development." However, it showed caution against hasty judgments until evidence is verified on whether Russia intentionally targeted Poland. The United States is focusing on establishing the facts in coordination with allies while working to block any possibility of escalation.

According to Reuters and others, U.S. Secretary of State Marco Rubio told reporters on the 13th (local time) before traveling to Israel and the United Kingdom that "this situation is unacceptable, unfortunate, and a dangerous development." He emphasized, "We do not want this to happen again."

Earlier, the Polish government said on the 10th that several Russian drones violated its airspace and that it shot down 3 to 4 of them. It is the first case since the outbreak of the Ukraine war that a NATO member has fired directly at a Russian military aircraft. Russia, however, denies the allegations, saying it never planned an attack on Poland.

Minister Rubio saw the launch of Russian drones itself as undeniably intentional. But he drew a line, saying it is necessary to closely examine whether the drones specifically targeted Poland. "If the evidence shows that, it would clearly be a highly escalatory move," he said. "There are several other possibilities as well. Before making a specific judgment, I want to confirm all the facts and consult with our allies," he added.

Minister Rubio's remarks are seen as recognizing the gravity of the matter while signaling he will not rush to conclusions that could spiral into a direct clash with Russia. Earlier, when U.S. President Donald Trump suggested the Russian drone incursion may have been a "mistake," Poland publicly pushed back, exposing a subtle divergence between the two countries. Poland's foreign minister told Reuters, "We hope the United States will take steps to show solidarity," pressing for a more active U.S. role.

NATO decided to further strengthen its defensive posture on the eastern front in response to this incident. The United States also reaffirmed its commitment to defend the alliance at the U.N. Security Council, saying it will defend "every inch of NATO territory."

Meanwhile, Minister Rubio will visit Israel during this trip to discuss Middle East issues. Regarding Israel's recent airstrike on Hamas leadership in Qatar, he said, "Of course we are dissatisfied, and so is the president." However, he said, "This will not change the nature of our relationship with Israel," making clear that the alliance will remain solid.
