Economic sanctions can have significant effects on national security by impacting a country's economy and its ability to sustain military capabilities. While intended to deter undesirable behavior, sanctions often lead to economic decline, causing political instability and social unrest within targeted nations. Such conditions may lead to increased aggression or unpredictable actions from sanctioned countries as they seek to mitigate economic pain. Additionally, prolonged sanctions can strain relationships with allies and complicate diplomatic efforts. Thus, while they serve as tools for foreign policy, they carry substantial risks for international security.
