The state’s response takes the form of intervention, when the threat is based beyond the borders of the target state (as with Israel’s 1982 involvement in Lebanon); or internal repression, when the threat is mainly domestic (as in Turkey with the PKK); or, as is typically the case, some combination of the two (as in Colombia).2 The nation-state was forged as a unique composite of law and strategy, the internal and external realms of authority; terrorism assaults both.3 We should hardly be surprised that states respond in the way that they were designed to respond.
