Poland Exits Mine Ban Treaty: A Fortress Built on "East Shield"

In a move that signals the end of a decades-long humanitarian consensus in Europe, Poland officially withdrew from the Ottawa Convention on February 20, 2026. By abandoning the treaty, Warsaw has cleared the legal path to stockpile and deploy antipersonnel landmines—a tool the Polish military now deems “indispensable” for stopping a potential Russian ground invasion.

The Strategic Pivot

This isn’t just about old-school explosives; it’s a core pillar of the “East Shield” (Tarcza Wschód) initiative. Faced with the reality of the war in Ukraine, Polish planners have concluded that high-tech surveillance isn’t enough to stop a massed tank and infantry assault.

The 48-Hour Threshold: Prime Minister Donald Tusk has emphasized that Poland can now saturate its 800km eastern border with mines in under two days if intelligence suggests an imminent strike.
The Stockpile Goal: The government is pivoting to domestic production, with a target of 5 to 6 million units to create a “no-go zone” along the frontiers with Kaliningrad and Belarus.

The Domino Effect: A Fragmenting Europe

Poland is the most recent—and most influential—NATO member to exit the ban. This creates a “mine-friendly” corridor across the alliance’s eastern flank, effectively re-drawing a defensive line reminiscent of the Cold War.

Nation	Recent Action	Reasoning
Poland	Withdrew Feb 2026	National survival / Deterrence
Baltic States	Withdrew Winter 2025	Regional “Deep Defense” strategy
Finland	Withdrew Jan 2026	Vast border security needs
Ukraine	Withdrawing	Active combat necessity

The Humanitarian Fallout

The decision has sent shockwaves through the international community. For thirty years, the Ottawa Convention was seen as a triumph of human rights over military utility.

The Critic’s View: Human rights organizations argue that mines are “indiscriminate killers” that don’t recognize a ceasefire. They fear Poland’s exit will encourage other nations to follow suit, effectively killing the global ban.

The Warsaw View: Polish officials argue that “morality” in 2026 is defined by the ability to prevent a Bucha-style occupation. They contend that modern, remotely-activated mines (which can be “turned off”) are more ethical than being defenseless.
