Tesis ini membandingkan upaya penanggulangan terorisme di Singapura, Malaysia, Filipina, dan Indonesia pasca-serangan 9/11 untuk mengetahui faktorfaktor di tingkat negara yang menjadikan Indonesia target serangan teroris transnasional terbanyak di Asia Tenggara dalam satu dekade terakhir. Data mengenai penanggulangan terorisme di keempat negara dianalisis secara kualitatif dengan menggunakan kerangka teori penggentaran. Hasil penelitian menyarankan bahwa agar tidak secara default menjadi target serangan yang paling menarik, Indonesia perlu memperkuat instrumen tumpul penanggulangan terorismenya, terutama dalam hal kontrol perbatasan maritim, kontrol imigrasi, mitigasi dampak serangan, dan regulasi finansial, sembari memperbaiki instrumen tajamnya melalui revisi bersyarat UU Anti-Terorisme dan penguatan sistem penahanan serta pengawasan pasca-penahanan.

This study compares post-9/11 counter-terrorism efforts in Singapore, Malaysia, the Philippines, and Indonesia to understand factors at the state level, which allows Indonesia to become the most attractive target of transnational terrorist attacks in Southeast Asia during the last decade. Data in this study are analyzed through the lens of deterrence theory using qualitative-comparative approach. This study suggests that in order to prevent Indonesia from becoming a default site for transnational terrorist attacks, it must strengthen its blunt counterterrorism instruments, especially with regards to maritime borders security, immigration control, impact mitigation, and financial regulation. Meanwhile, it must improve its sharp instrument, namely intelligence-driven law operation, by cautiously strengthening its anti-terrorism legislation and improving its detention and post-detention system.
