Obviously it is still impossible and will be impossible for some time to make a definitive legal research into the problem of neutrality during the present European war. Most important facts and documents are still unpublished, inaccessible or shrouded in the fog of contradictions and propaganda. The duration and the outcome of the war are still uncertain and nobody can foresee what type of world will emerge from this war and what the future of neutrality in this type of world will be.
