"No doubt, the prevailing sentiment throughout Germany is in favour of territorially reducing France. After all the people have suffered, and with the ordinary inducements of some fresh acquisitions, it is not wonderful that it should be so; but it is one thing to wish the thing done, and another to maintain it when done; and, in calculating the chances of the latter, we ought to be aware that none of these Powers can, for any time, keep up war establishments, or, having once laid them down, find the means of speedily resuming them; and that, if the course adopted materially increases the chances of early war with France, these acquisitions may be of short duration, whilst our chances of an interval of peace will be diminished, and we may be obliged, in order to keep France within any bounds, to take the weight of the war, in a pecuniary sense, upon ourselves."
