The Russian invasion of Ukraine in 2022 immeasurably disturbed the European security landscape greatly fuelling fear of Russia’s neo-imperialistic ambitions, particularly in the former Soviet sphere of influence. In Eastern Europe, especially in the Baltic states and Poland, these fears have grown steadily since Russia’s hybrid forms of aggression against Ukraine in 2014.

In particular, Poland has felt threatened by various hybrid threat scenarios since the beginning of Vladimir Putin’s full-scale invasion of Ukraine in 2022, including a potential attack on its own territory. Poland’s response to the war in Ukraine has been and continues to be influenced by both geographical and historical considerations.

With a border shared with Russia’s exclave, Kaliningrad, and the escalating tensions since Russia’s annexation of Crimea in 2014, the fear of a Russian invasion through the Suwalki Gap, a crucial Polish-Lithuanian border, emerged as a concerning potential contingency since the collapse of the Eastern bloc.

As a result, Poland has decided to act decisively.  In concrete terms, this has materialised as the massive expansion of its defence forces and staunch support for its attacked neighbour.
