"Under some circumstances attempts at deterrence can "backfire" when a potential attacker misinterprets the state's deterrence measures as a "prelude to offensive measures". In such cases the security dilemma can arise generating perceptions of a "first strike advantage". According to Huth "most effective deterrence policies are those that decrease the expected utility of using force while not reducing the expected utility of the status quo; optimally deterrent policies would even increase the utility of not using the force." It is more likely that deterrence will succeed if the attacker finds deterrence threat "credible" and a credible deterrence threat might not necessarily be a military threat.
