The post-communist NATO member states from Central and South-Eastern Europe (CSEE) comprise a group of 11 NATO/EU member states, from the Baltic to the Adriatic and Black Sea. The twelfth and thirteenth NATO member states from the region are Albania and Montenegro. The afore-mentioned NATO/EU member states have mostly shown a similar stance towards the Eastern Partnership Policy. However, since 2014, these states have shown more diverse stances, albeit declaratively supporting the anti-Russian sanctions. Due to the difference in stances towards Russia, the “New Cold Warriors” (Poland, Estonia, Latvia, Lithuania and Romania) and the “Pragmatics” (Hungary, Slovakia, Slovenia and Bulgaria), will maintain a mostly common course towards Russia and the Eastern Partnership states because they have to. The Czech Republic, although hosting a part of the US anti-ballistic missile shield, is not a genuine “New Cold Warrior”, while in 2016 Croatia effectively became one.
