Dr Julian Lewis: As a relative newcomer to the sponsorship of the concept of military deterrence, does the Foreign Secretary appreciate that the best chance of deterring an aggressor is to be as specific as possible in stating what military action will follow if that aggressor fails to comply with requirements? Therefore, when the right hon. Gentleman talks about the possibility of military action against Serbia, will he spell out clearly whether he means that it will be simply air action, unsupported by anything else? Does he mean that such action will take place only in the disputed area of Kosovo, or will it extend to Serbia itself?
