One of my favorite writers of fiction and non-fiction, Ralph Peters, suggests tiered sovereignties for forging order and safety in the post 9/11 world:
Level One: Every government, from Mexico to India, that respects the will of its people through democratic institutions, works for the betterment of its citizens, demonstrates progress toward respect for human rights and strives toward the rule of law deserves continued recognition of its full, legal sovereignty.
Level Two: States that cannot control their own territory, that lack the ability to protect their own citizens or to prevent international terrorists and other criminals from using their territory as a refuge, would be able to claim only partial sovereignty. More capable, rule-of-law states would have the right to intervene for limited purposes to bring killers and other criminals to justice. In every other respect, these weak, but well-intentioned states would enjoy the traditional privileges and protections of sovereignty.
Level Three: Regimes that refuse to enforce the rule of law inside their borders, that knowingly harbor terrorists and criminals, that behave aggressively toward their neighbors or that abuse their own citizens would forfeit their territorial sovereignty and their right to govern. Period.
Read it all. Peters has written an important column, codifying what we seem to be heading towards, anyway.
