Report Urges Better Insurance Against Cost of Terror Attacks

Larger states with bigger budgets and insurance markets, like Britain and France, are less inclined to sign up to such a scheme than neighbors less able to shoulder the economic impact of a major terror strike alone, Vignial-Denain said.

In the end, groups of smaller states are more likely to set up regional schemes to mutualize their terror risks, she predicted. "But whether we would have to wait for another attack before that happens, only the future will tell."
