France and Poland signed a landmark defence treaty today in Nancy, committing to mutual military support in the event of an armed threat.
The agreement, described by Polish Prime Minister Donald Tusk as “groundbreaking,” also opens the door to discussions on extending France’s nuclear deterrent to Poland.
The treaty reflects growing European efforts to bolster regional security amid concerns over U.S. commitment to NATO. Poland, NATO’s top defence spender at 4.12% of GDP, is seeking to diversify its security partnerships.
French officials clarified that any nuclear cooperation would complement, not replace, existing U.S. guarantees.
The treaty also includes provisions for joint military exercises and defence industry collaboration.
The signing coincides with Russia’s Victory Day parade, underscoring the shifting security dynamics in Europe.
