Research on terrorism is a sensitive and critical aspect globally from a security perspective that calls for an action policy. Since 9/11, terrorism has been considered a high risk or a disaster for global governance without geographical exceptions. Its association with political and economic and the severity of causalities it causes leaves a worrisome and long-lasting impact on global cohesion and peacefulness, just like a natural disaster would. This study unveils the political and policy measures, public expenditures, and likely external intervention determinants and their association with terrorism in the panel data of 151 countries from 2012 to 2022. The statistics of SGMM say that political stability is the most impactful and significant factor in reducing terrorism globally. External intervention from political agencies and economic forces is the second-most influential factor in mitigating terrorism incidents. The study further observes that the effectiveness of counter-terrorism measures and policy implementation has proven less impactful in mitigating terrorism. The innovative findings of this study state that government expenditures toward basic facilities are impactful in deterring terrorism but do not have a significant role in global analysis. The study recommends that the EU and America should collaborate and work on Asian and African regional security, rather than invade state security and sovereignty as part of their collective measures of counter-terrorism. A collaborative effort helps eradicate external evil forces or groups and sustain the state and global peace.
