Europe has to face new problems. Since the WWII catastrophe, it has renounced to internal wars. And, under the American umbrella, it can provide for such an ambition. It stands for the voice of Kant's vision of international relations. However, as it is protected by USA, the European position as regard to risks of war arising may seem ambiguous. If it wants to be credible, it has to give good example at its borders. But, two cases, in Caucasia and in Africa, show that it is not so. This paper aims at recalling how the ‘geographic-induced’ war pressures, during the European history, above all since 1800 (the Napoleonic wars) and even more since 1914 (the first world war) were. This first enables to look at the way the situation has essentially evolved, and secondly how that very situation can modify the verdict of the Modelski-Goldstein's theory about risks of war in the world for the coming fifty years.
