International sanctions can significantly affect a country's politics by restricting trade and economic activities, thereby applying pressure on the targeted government. Sanctions aim to deter specific behaviors such as human rights violations, aggressive military actions, or nuclear proliferation. While they may weaken a regime's resources, they can also lead to unintended consequences, including humanitarian crises and increased nationalism. The effectiveness of sanctions often depends on international cooperation and the targeted country's resilience, making their impact complex and multi-faceted.
