The question was, how to secure a guarantee against this. It had to be of a territorial nature, because the guarantees of foreign powers were not of much use to us, such guarantees having at times been subject to supplementary and attenuating declarations. One might have thought that all Europe would have felt the need of preventing the ever recurring wars of two great and civilized peoples in the heart of Europe, and that it would have been natural to assume that the simplest way to do this was to strengthen the defences of that one of the two participants who doubtless was the more pacific. I cannot, however, say that at first this idea appeared convincing everywhere. Other expedients were looked for, and the suggestion was often made that we should be satisfied with an indemnity and the razing of the French fortresses in Alsace and Lorraine. This I always opposed, because I considered it an impracticable means of maintaining peace. The establishment of an easement on foreign territory is very oppressive and disagreeable to the sense of sovereignty and independence of those who are affected by it. The cession of a fortress is felt scarcely more bitterly than the injunction by foreigners not to build on the territory which is under one's own sovereignty. French passions have probably been excited more frequently and more successfully by a reference to the razing of that unimportant place of Hüningen than by the loss of any conquered territory which France had to suffer in 1815. I placed, therefore, no confidence in this means, especially since the geographical configuration of this advanced outpost--as I took the liberty of calling it--would have put the starting place for the French troops just as near to Stuttgart and Munich as it had always been. It was important to put it farther back. Metz, moreover, is a place of such a topographical configuration, that very little art is needed to transform it into a strong fortress. If anyone should destroy these additions to nature--which would be a very expensive undertaking--they could be quickly restored. Consequently I looked also upon this suggestion as insufficient.
