What did we get wrong? This is a daunting question for the governments of France, Germany and several other European countries. When the Ukrainians are liberated from Russian occupation and start reconstructing their country and their lives, it will be high time for us to engage in a serious overhaul of our conception and practice of security-keeping on our continent. We will need to define a common strategy toward a defeated state and a despondent society in the Federation of Russia. Only with a thorough analysis of wrong assessments and failed policies shall we be able to build a strong, comprehensive security system in Europe and beyond.
