NATO in 2025: 32 Members, Trump’s Pressure and Europe’s Buildup
Finland joined in 2023. Sweden in 2024. Now NATO has 32 members — and a fundamental question about whether the United States will remain a reliable partner. Europe’s response: the largest peacetime defense spending surge since the Cold War.

Finland and Sweden: Why They Joined
Finland — April 2023
Finland shares a 1,340 km border with Russia — the longest EU–Russia border. Maintaining military non-alignment since 1948, Finland shifted dramatically after Russia’s 2022 invasion of Ukraine.
Public support for NATO membership rose from 26% in January 2022 to 76% by May 2022 — one of the fastest opinion shifts on a major policy question in recorded polling history.
Finland already spent 2.4% of GDP on defense in 2024, has universal male conscription, and has significant reserve forces. It is widely considered one of NATO’s most credible new members.
Sweden — March 2024
Sweden had been non-aligned since the Napoleonic era — over 200 years. Its path to NATO was complicated by Turkey’s objections over Kurdish political groups, resolved with diplomatic concessions in early 2024.
Swedish public support went from 35% in 2021 to 59% by late 2022. Sweden brings advanced military capabilities including JAS Gripen fighter jets and submarine expertise valued by NATO planners.
Sweden’s entry closes a strategic gap in the Baltic Sea, giving NATO near-complete control of the Baltic region and significantly complicating Russian naval access from Kaliningrad.
Trump’s Burden-Sharing Pressure
Donald Trump has made NATO burden-sharing a central complaint since his first term. During his 2024 campaign he stated he would “encourage” Russia to do “whatever the hell they want” to NATO allies that don’t pay enough — a statement that shocked European capitals and accelerated defense spending pledges.
American Public Opinion
- 70% of Americans: Europe should pay more for defense (Gallup 2024)
- 58% of Americans: still support US NATO commitment
- 47% of Republicans: US should stay in NATO (down from 68%)
- 82% of Democrats: US should honor Article 5 obligations
European Reaction
- EU ReArm Europe: €800 billion defense package (2025)
- Germany: €100B+ Sondervermögen defense fund
- Poland: targeting 4% of GDP by 2026
- France: nuclear umbrella proposals for EU partners
- Baltic states: already 3%+ of GDP before Trump pressure

The European Pillar: Can Europe Defend Itself?
“Strategic autonomy” — the idea that Europe should be able to defend itself independently — has shifted from Macron’s fringe idea to mainstream EU policy in three years. But the gap between aspiration and capability remains large.
| Capability Area | Current European Status | Gap vs. US |
|---|---|---|
| Nuclear deterrence | France only (UK outside EU) | Massive — US has 5,550 warheads vs. France’s ~290 |
| Intelligence (ISR) | Partly via individual states | Large — US provides 80%+ of NATO ISR capability |
| Heavy airlift | Limited EU fleet | Significant — US C-17/C-5 fleet dwarfs EU capacity |
| Air defense (SHORAD/THAAD) | German-led European Sky Shield emerging | Moderate — improving with new investments |
| Ground forces | Poland, France, Germany building up | Manageable — EU has large conventional forces |
| Defense industry | Fragmented but investing heavily (KNDS, Rheinmetall, Dassault) | Large for high-end systems; narrowing for munitions |
