I acknowledge there's pattern of high-profile assassinations in history that raise questions and seem interconnected. However, attributing them to a small covert group is a logical leap. What would convince you they're not conspiring together? As for international organizations, my point is that even ratified and official organizations are not immune to political pressures and special interests. How do we ensure transparency, efficacy, and fairness when the existing entities can't do that sufficiently well to maintain unipolarity?
