ABSTRACT
The first decade of the twenty-first century has been characterized by sudden “wake-up calls” on such serious issues as environmental degradation,1 the futility of war as a strategy for instituting democratic governance anywhere in the world,2
anti-poverty campaigns, etc. Nonetheless, it is arguable that few subjects have exercised general public and legal concerns as much as the question of what constitutes an “appropriate, efficient and sufficient” response to the increasing threat of international terrorism. The response to this threat is the burden of national governments. Therefore, the “appropriate, efficient and sufficient” test is necessarily a legal question because conduct of States everywhere is measured always by the requirements of the rule of law.3
