Haven't read the book yet, but have to say I know exactly what it is centered on: the need to recognize the 'new' international law. As soon as the Internet appeared in peoples' lives and fastforwarded the globalization, the world was never going to be the same. International law as it was perceived in the 20th century also was bound to change. Increasingly the international law, no matter how people around the world understand it, is going through a restructuring. Since the law generally is a product of the society shaping it, international law was going to be shaped by the 'international community.' As spread out, large and diverse as that 'community' is, it is interconnected by very strong ties glued together by the age of information. So, in some sense the Internet fostered a new stronger 'international law'. Most people unquestionably will have exposure to it one way or the other. On the other hand, because of the Internet there are more voices heard out there in the 'international community', that have the power and ability to shape that same international law. No longer is the international law a product of the industrialized world, Western civilization... Individuals from once marginalized countries and states now have a lot of say on what is going to be the 'international law' of the century. Because individuals from various cultures and countries may not always agree on many things, the globalization may 'weaken' the concept of international law. International law was always based on the aspirational postulate of 'universality', or in some sense, 'e pluribus unum'... The more the players, the harder for it to maintain its functions in a coordinated manner. It remains to be seen, how the fact that so many 'players' from such diverse corners of the world have come to the table, will ultimately shape the future of international law. Turning more 'democratic' and 'open', it does not necessarily become stronger. As we know, all democracies generally are more fragile than monarchies or oligarchies... Yet, if only a few 'chosen' continued the monopoly over the 'international law', that would subvert the very purpose of its existence.
I would recommend to read this book and think more about what is awaiting in the future for 'international law'.
