Refugees from Ukraine line up to enter Poland on Feb. 28 at the border crossing in Medyka, Poland.
While Poland faces no immediate threat of Russian military aggression, it is exposed to unconventional attacks from Moscow that will keep tensions high in the coming weeks. The events in Ukraine could also negatively impact the Polish economy, while the influx of migrants from Ukraine could produce a nationalist backlash. Poland's primary geopolitical concern is a potential Russian attack, which explains why it is one of the most hawkish EU and NATO member states when it comes to calling for sanctions against Russia. But Poland faces no immediate threat of Russian invasion because it is covered by NATO's collective defense framework, and Russia is not interested in going to war with the alliance. Russia's response to EU sanctions, however, will likely include unconventional aggressions such as cyberattacks against governments and businesses and disinformation campaigns.
