The short answer to both questions is no. We are not arguing that we are seeing the beginning of the end of the nation-state. Nor would we be so naive as to suggest that human security is exclusively about intra-state conflict. Inter-state conflict is not, unfortunately, going to disappear any time soon. In a sense, we see national security and human security as two sides of the same coin.
Human security means building security from the bottom up.
To use an analogy from economic theory, it is micro-security. Looking down the road 30 or 40 years, one can imagine the emergence of another mega-threat or two. But at least for now, it is the myriad of micro-conflicts that demand our attention. These are the conflicts of the warlords, fought over diamonds. These are the wars of the ethnic cleansers, where killing is a matter of colour, race or religion.
