The monograph examines contemporary populism and neopopulism, 21st century socialism, and a nonstate actor (al-Qaeda) seeking regional and global hegemony. They first, paramilitary gang permutations in Colombia that are contributing significantly to the erosion of the Colombian state and its democratic institutions, and implementing the anti-system objectives of their elite neo-populist sponsors; second, Hugo Chavez’s use of the New Socialism and popular militias to facilitate his populist Bolivarian dream of creating a mega-state in Latin America; and, third, al-Qaeda’s strategic and hegemonic use of political-criminal gangs to coerce substantive change in Spanish and other Western European foreign and defense policy and governance. Lessons derived from these cases demonstrate how gangs might fit into a holistic effort to force radical political-social-economic change, and illustrate how traditional political-military objectives may be achieved indirectly, rather than directly.
