Pooling equilibriums result with two types of ex post regret: P-regret, where the government concedes to political types that would not subsequently attack; and M-regret, where the government does not concede to militant types that subsequently attack at greater levels. Avoidance of such regret defines a measure of the value of intelligence. Counter-terrorism policy can then be characterized in terms of whether a government should focus on increased intelligence versus increased security (hardening targets). The recommended use of asset freezing is also evaluated in terms of the resources required by terrorists to achieve the various equilibriums. Finally, this article supports the empirical finding of intertemporal substitution of resources by terrorists, concerned with the level of government response to their attacks
