Geopolitical blocs are groups of countries that come together based on shared interests, political goals, or economic ties. These alliances can influence global politics and trade, as member nations often collaborate on issues like security, economic development, and environmental policies. Examples of such blocs include the European Union and the North Atlantic Treaty Organization (NATO). These alliances can also shape international relations by creating a balance of power. Countries within a bloc may support each other in diplomatic matters, while those outside may find themselves at a disadvantage. Understanding these blocs is essential for analyzing global dynamics and conflicts.
