It is a direct result of the Glorious Revolution. The power of ideas.
Chad, Ethiopia and Somalia are devastated by civil war, unrelenting factional terrorism, genocide, religious totalitarianism. Somalia in particular is controlled by roving gangs with allegience to various and numerous murderous chieftans. Egypt, Saudi Arabia, Libya, Syria, Iran interfer shamelessly in the affairs of Chad, Ethiopia and Somalia and never to any positive consequence. I would not hold up C, E & S as touchstones of liberty. And without liberty, you cannot have democracy, no matter what the propaganda of the elites.
It is nice to think that the European Union could be powerful, but it chooses not to be. China is growing in influence and it has the will to project its ideas. Iran has been very powerful for a very long time, whether Europe noticed or not, and it has the will to project its ideas.
China, Iran, the European Union and increasingly the USA all have difficulty lately "going in one direction."
But I would not count out India as the real rising star. That is my odds-on favorite for the future.
