I feel like the problem is just the way power is distributed to nation-states with money. We've got to start working towards a world where nation-states aren't forced to compete with each other economically--instead where they are incentivized to work together economically and compete over citizens. Nation-states serve a purpose, as religion did/does. But the scope of that control must change as civilization does. I feel in a couple years they may look back on this age as we do now with the crusades.
