Finland has joined the French nuclear deterrence initiative, and work on this cooperation began last week. President Alexander Stubb said such engagement should broaden Helsinki's understanding of the risks and consequences of security decisions and strengthen collective deterrence. The concept of "progressive deterrence" in Europe was introduced by French President Emmanuel Macron. Finland became the tenth participating European country (previously joined by Norway, Sweden, Denmark, Great Britain, Germany, Netherlands, Belgium, Greece and Poland). The Baltic states are also discussing joining the program.
