What we more often fail to observe or acknowledge about the generally messy and entropic state of international relations and an apparent inevitability of internecine conflict is that, as a whole, human civilisation is autonomously calculating and computing the optimal means and methods for self-propagation and systemic continuity.
Homeostasis is not engendered through aspiration towards static or unchanging aand final states of organisational or developmental closure. The international society of states (such as it is) finds itself endlessly competing with an intractable, irreducible orientation of information and energy-processing systems to seek their own optimal environmental continuity and contextual tenure.
The key insight is that optimally concise algorithmic self-propagation is the natural heir of abstract logical systems as much as of material or biological systems. Psychological factors and dependence upon at least partially-invalidated and anachronistic paradigms of thought bind us to attempt to control that which, if approached with intelligence and mature humility, would quite adequately and efficiently manifest self-control and optimal efficiency.
One does not require extensive experience with the psychological inertia of hierarchical bureaucracies to comprehend that their own narcissistic self-interest trumps their defined purposes and that this, in a nutshell, is the single greatest inhibition to the indefinite tenure of a successful and thriving planetary civilisation.
