Strategic alliances profoundly influence global politics by altering power dynamics and shaping international relations. Countries may form alliances for various reasons, such as mutual defense, economic benefits, or addressing global issues like climate change and terrorism. These alliances can enhance a nation's security, increase bargaining power, and promote stability in a region. However, they may also lead to polarization, where rival alliances could emerge, creating potential conflicts. Alliances can facilitate cooperation through treaties and negotiations, but they can also result in dependencies that may constrain a country’s independent foreign policy decisions.
