Russia's full-scale invasion of Ukraine precipitated a tectonic shift in European security dynamics, ending a relatively peaceful post–Cold War phase and moving the epicenter of European security eastward, to Poland. Janusz Bugajski explores the nature and context of Warsaw's determined efforts to shape NATO's eastern policy and to build a strong, modern military able to resist Russian aggression.
