Some synonyms for counter-terrorism include anti-terrorism, counterinsurgency, counter-extremism, and counter-radicalization. These terms all refer to the same basic idea of preventing and responding to terrorist threats. Anti-terrorism and counterinsurgency are more focused on military action, while counter-extremism and counter-radicalization are more focused on addressing the underlying causes of terrorism, such as religious extremism or political ideology. Regardless of the specific terminology used, the goal of counter-terrorism is always to keep people safe by preventing terrorist attacks.
