Poland Invokes NATO Article 4

Introduction

Poland has triggered alarm across Europe after dozens of Russian drones allegedly crossed into its airspace. Prime Minister Donald Tusk responded by invoking NATO Article 4, a treaty provision demanding consultations when a member’s security might be threatened. With NATO Article 5 also in the background of public discussion, many are asking: is this the start of a larger conflict?

Who Is Involved & What Happened

On the night of September 9-10, 2025, Poland reported that 19 drones entered its territory during a major Russian aerial attack on Ukraine. Reuters+3Reuters+3Al Jazeera+3
Polish and allied jets scrambled—including Polish F-16s and Dutch F-35s, plus support from AWACS and surveillance aircraft. Some drones were shot down. Reuters+2Reuters+2
The breach is causing widespread concern, not only for Poland but for NATO as a whole. Prime Minister Tusk described the incident as a “large-scale provocation” and said Poland has asked NATO to activate Article 4. Reuters+2AP News+2

What Is NATO Article 4 and How It Differs from Article 5

Feature	Article 4	Article 5
Purpose	Allows any NATO member to request consultations if it believes its territorial integrity, political independence, or security is threatened. NATO+2AP News+2	The collective defense clause: an attack on one member is considered an attack on all, possibly triggering joint defensive actions. NATO+2AP News+2
Obligation	No automatic military response; the member gets to bring the issue up for debate among all allies. NATO+2Bloomberg.com+2	Requires consensus among allies; could involve military, political, or other forms of defense. Reuters+3NATO+3Bloomberg.com+3
History / Use	Invoked several times in NATO history for threats or perceived security risks. Wikipedia+2AP News+2	Invoked only once—after the September 11, 2001, attacks on the U.S. NATO+1

So in short: Article 4 = “Let’s meet and figure this out,” Article 5 = “We respond together.”
