The Passport Paradox: Borrowed Sovereignty and the Limits of Bilateral Deterrence in Mossad-Attributed Operations, 1973–2010

Trusted foreign passports enable clandestine mobility, yet repeated exposure and protest have not ended their misuse in covert operations. This study asks why non-recurrence assurances and bilateral penalties failed to remove that operational option. It uses a structured, focused comparison of the Lillehammer affair (1973), the attempted assassination of Khaled Mashal in Amman (1997), New Zealand’s passport affair (2004), and the Dubai killing of Mahmoud al-Mabhouh (2010), drawing principally on commissions of inquiry, parliamentary records, security reviews, court records, and official statements. The findings show that passports provide more than cover: they allow operatives to appropriate the issuing state’s sovereign credibility, mobility privileges, and institutional trust while shifting the costs of exposure onto issuing governments and innocent holders. Diplomatic and technical responses sometimes protected a particular credential, but remained bilateral, delayed, and reversible, leaving access to a wider pool of substitutable high-trust identities. This mismatch is conceptualized as fragmented deterrence, a middle-range framework distinguishing issuer-specific denial from system-level cessation. The comparison concludes that biometric hardening alone cannot resolve the passport paradox. Effective deterrence also requires cross-national coordination as digital credentials, AI-assisted verification, synthetic identities, and deepfake-enabled fraud shift vulnerability from the booklet to enrollment, data consistency, and trust governance.
