Small states are important and visible players in international politics. Their power is limited, and their economy and military capability may not match those of their larger neighbours, but small states enjoy certain advantages that increase their abilities to influence international politics. This article tries to show and explain how small states can act and exploit their advantages in a wider international arena. The main aim is to show ways and methods for small states to act and pursue their policy goals. This article analyses the behaviour of small states inside two major European security actors: NATO and the EU. Several examples will be presented in detail, namely, air policing in the Baltic states and the Lithuanian Presidency in the European Council. These examples clearly show the achievements and failures of small states in international politics.
