Our article is so long, that we cannot discuss the questions, whether Napoleon III. is not animated by the desire of vengeance, and whether, having chastised Russia and Austria, he will not turn his arms against Prussia and England. Our opinion is that he will do nothing of the kind. Prussia is not likely to afford him any occasion for war; and if he should make one, he would have to fight all the other German powers at the same time, and perhaps Russia. The only chance that exists for a Prussian war is to be found in the wrath of the Germans, who, at the time we write, have assumed a very hostile attitude towards France, and wish to be led from Berlin; but the government of Prussia is discreet, and will not be easily induced to incur the positive loss and probable disgrace that would follow from a Russian invasion, like that which took place in 1759. As to England, the Emperor would be mad to attempt her conquest; and he knows too well what is due to his fame to engage in a piratical dash at London. An invasion of England can never be safely undertaken except by some power that is master of the seas; and England is not in the least disposed to abandon her maritime supremacy. There would have to be a Battle of Actium before her shores could be in danger, and she must have lost it; and no matter what is said concerning the excellence of the French navy, that of England is as much ahead of it in all the elements of real, enduring strength, as it has been at any other period of the history of the two countries.
