The biggest spiritual revolution will take a strong shape during this decade based on values of kindness, compassion and empathy. This is because people will gradually realize that almost all the current problems including mental diseases (depression), religious conflicts, political turmoil, economic and military warfare are happening because of selfish living, and very narrow mindset. Though technology and comfort wise humans have progressed a lot over last couple of centuries but mentally the same degree of evolution hasn't happened. (if it had, we’d have no physical borders/huge national militaries etc. when in technology we’ve broken all distance and boundaries) The fault lines are increasingly visible again which may cause WW3 but spiritual revolution is coming with or without WW3.
