* Our summary is short, simple and pragmatic. It allows you to have the essential ideas of a big book in less than 30 minutes.

*As you read this summary, you will discover that in today's world, the only certainty is that there is none: uncertainty is permanent.

*You will also discover : that uncertainty is a necessary part of decision making, otherwise life would be a one-way street; that uncertainty finds its source in the freedom of the other to act as he or she pleases; that to decide is above all to know how to adapt; that uncertainty engenders innovation and allows human intelligence to express itself.

*To be effective, a leader, whether military or civilian, has no choice but to conceive and conduct his action by taking this constant into account. Even the most effective technology or intelligence operations do not protect you from the unexpected. Based on his personal experience, General Vincent Desportes, former director of the École de guerre, lecturer and teacher at Sciences Po and HEC, believes that while we must take into account uncertainty and the ever-changing situations in which it places the decision-maker, we must not resign ourselves to it. It is possible to apprehend this uncertainty, to tame it, and even to use it (because we must never forget that it also affects the adversary), in order to give ourselves more chances of success.
