Poland
PL · Central-Eastern Europe · NATO member since 1999 · EU member since 2004
Poland is NATO’s largest eastern flank member and the alliance’s most significant conventional military power in Central Europe. Since Russia’s 2022 invasion of Ukraine, Poland has undergone the fastest military expansion of any NATO member, raising defence spending to approximately 4.7% of GDP — the highest in the entire alliance, outpacing even the United States — and committing to build the largest ground force in Europe.
Poland’s geopolitical position has always been defined by its location between Germany and Russia, two powers that have historically threatened its sovereignty. This geography produces a distinctive foreign policy: deeply Atlanticist (prioritising US commitment over European strategic autonomy), strongly pro-Ukraine, and consistently hawkish on Russian threat assessments. Warsaw was warning about Russian intentions long before most Western capitals took the threat seriously.
Poland joined NATO in 1999 alongside Hungary and the Czech Republic in the alliance’s first post-Cold War enlargement round. It joined the EU in 2004 as part of the largest single enlargement in the bloc’s history. Poland hosts permanent NATO Enhanced Forward Presence (eFP) battlegroups and a permanent US Army V Corps headquarters in Poznań — the first permanent US corps headquarters in Europe since the Cold War. It is part of the Bucharest Nine (B9) group of eastern flank states that coordinate on Russia policy.
Poland’s defence budget has reached approximately $34 billion, making it NATO’s fifth-largest absolute spender (behind the US, Germany, UK, and France) but the undisputed first in GDP percentage terms at approximately 4.7% — higher than any other alliance member (NATO, 2025). Poland is acquiring F-35A fighter jets (32 aircraft), M1A2 Abrams tanks (366 ordered from the US), K2 Black Panther tanks (980 ordered from South Korea in the largest arms deal in Polish history), and HIMARS rocket artillery systems.
The Polish Armed Forces have approximately 185,000 active personnel with a stated goal of reaching 300,000 — which would give Poland the largest army in Europe west of Russia. Poland does not possess nuclear weapons but participates in discussions about NATO nuclear sharing arrangements.
Russia: Poland views Russia as an existential threat. Following the 2022 invasion of Ukraine, Poland became one of Ukraine’s largest per-capita military donors and has called consistently for stronger NATO deterrence on the eastern flank, including permanent rather than rotational allied troop deployments.
Belarus: Poland shares a 418km border with Belarus. Since 2021, Belarus has deliberately facilitated illegal migrant crossings into Poland as a hybrid warfare tool — a strategy widely attributed to Lukashenko at Russian direction. Poland has constructed a border barrier and deployed military forces to the frontier.
EU rule of law: The previous Law and Justice (PiS) government (2015–2023) was in prolonged conflict with EU institutions over judicial independence. The current Tusk government has moved to restore EU relations and unlock frozen EU recovery funds.
Germany: Poland has periodically sought WWII reparations from Germany, with figures cited as high as $1.3 trillion. The issue is politically live domestically but has not progressed diplomatically.
Poland is the clearest example of a state whose foreign policy is driven by what scholars call “geopolitical memory” — the institutionalised recall of historical trauma shaping strategic culture. Having been partitioned three times and occupied by both Nazi Germany and the Soviet Union in the 20th century, Polish strategic culture is defined by a deep suspicion of both Berlin and Moscow and a strong preference for hard US security guarantees over softer European multilateral frameworks. Realists would note that Poland’s current military build-up is a textbook case of internal balancing against a perceived threat.
