"This monograph explains the linkage of contemporary criminal street gangs (that is, the gang phenomenon or third generation gangs) to insurgency in terms of the instability it wreaks upon governments and the concomitant challenge to state sovereignty. Although differences between gangs and insurgents regarding motives and modes of operations exist, this linkage infers that gang phenomena are mutated forms of urban insurgency. In these terms, these 'new' nonstate actors must eventually seize political power to guarantee the freedom of action and the commercial environment they want. The common denominator that can link the gang phenomenon to insurgency is that some third generation gangs' and insurgents' ultimate objective is to depose or control the governments of targeted countries."
