The term "Western blocs" refers to groups of countries that aligned with the United States and its allies during the Cold War. These nations shared similar political ideologies, primarily democracy and capitalism, and worked together to counter the influence of the Soviet Union and its allies, known as the Eastern bloc. Key organizations within the Western blocs included NATO (North Atlantic Treaty Organization) and the European Union. These alliances facilitated military cooperation, economic collaboration, and cultural exchange among member states, promoting stability and security in the Western Hemisphere and beyond.
