Perhaps we are already in the beginning stages of WW-III, between Islamic/Arab fundamentalist and the rest of the world, with the "battlefront" being anywhere and everywhere. If that is the case, then our best tactic may be the current approach of using the military as a force for developing good-will between nations and for aiding in projects - like building schools and roads - that are requested by the nations where conflict is most prevalent.
One way or another, I think the world is on the verge of revolution.
Worst case scenario
: Armageddon and the collapse of the Western economies. There are several scenarios I can see triggering that, the most likely being Israel attacking Iran's nuclear plants. If that were to happen, it would trigger an immediate worldwide oil crisis (70% of the world's oil supply goes through the Straights of Hormuz); all of the risk indicators would go off the dials, and the banks would close. Civil order would break down almost immediately as a result because the police and military were not being paid. And anarchy would ensue on a worldwide scale. The other possible scenario is the overthrow of the Pakistani government by Islamic radicals who would then have access to a real nuclear arsenal and necessitating military intervention in the volatile North Asian theatre. Both these scenarios are plausible, some would even say they were likely.
Best case scenario:
a breakthrough in the understanding of the fundamental nature of matter and energy that results in a clean energy source with zero environmental impact; perhaps usable fusion energy. This would go a long way to removing many of the tensions that underlie the current conflicts in the world. Given sufficient co-operation, the prospect of universal prosperity could be realised if this is discovered. It is going to be almost impossible without it.
: the world will muddle along albeit with greatly elevated levels of economic uncertainty, barely contained regional conflicts, static or declining living standards, and rapidly emerging large-scale problems of food, water and energy security. The impact of the possible fall in living standards should not be underestimated - ever since the Industrial Revolution commenced, standards of living have actually been on the rise across the board (believe it or not.) Is it possible that this trend peaked in 2007?
I frankly doubt that the Baha'i or any other cultural group or spiritual movement will have a huge impact in light of the immensity of the challenges that the world faces today. But on the other hand, at least they are promoting discussion of some of the root causes of the predicament we're in. And they deserve credit for that.
