Most observers believe that the 'democratic rules of the game' provide a peaceful means for resolving political conflicts. This may be true but not all groups or even single individuals in democratic societies need play by these rules. This analysis uses two data sets: one that classifies most countries of the world based on how they were ruled in the mid-1980s, and the other on the frequency with which their nationals either perpetrated or were victimized by terrorists attacks, to investigate the relationship between terrorism and democracy. The findings suggest that stable democracy and terrorism go together. An analysis of the data reveal that terrorist attacks occur most often in the world's most stable democracies, and that, further, both the perpetrators and victims of those attacks are citizens of the same democracies.
