This book is a remarkable clarity. Synthetic enough to take stock of the present world, but relatively developed to not be too superficial, I do not see errors and faults if nimbreuses some have seen (I did find two but very margin ). One can occasionally regret the lack of development in conflicts whose origins are sometimes distant. I do not put 5 stars because the proposed scenarios by looking on the right of each conflict are sometimes simplistic and do not bring much. Excellent overall.
