I am aware that an argument of this sort is singularly liable to misrepresentation. Militant patriotism rejects it with scorn. It is said to involve an ignoble degree of truckling to foreign nations. It involves nothing of the kind. I should certainly be the last to recommend anything approaching to pusillanimity in the conduct of the foreign affairs of my country. If I thought that the introduction of a policy of Protection was really demanded in the interests of the inhabitants of the United Kingdom, I should warmly advocate it, whatever might be the effect produced on the public opinion of other countries. British Free Traders do not advocate the cause which they have at heart in order to benefit the countries which send their goods to Great Britain, but because they think it advantageous to their own country to procure certain foreign products without any artificial enhancement of price.[64] If they are right in coming to this conclusion, it is surely an incidental advantage of much importance that a policy of Free Trade, besides being advantageous to the United Kingdom, tends to give an additional element of stability to the British Empire and to preserve the peace of the world. From the dawn of history, uncontrolled commercialism has been one of the principal causes of misgovernment, and more especially of the misgovernment of subject races. The early history of the Spaniards in South and Central America, as well as the more recent history of other States, testify to the truth of this generalisation. Similarly, Trade--that is to say exclusive trade--far from tending to promote peace, has not infrequently been accompanied by aggression, and has rather tended to promote war. Tariff wars, which are the natural outcome of the protective system, have been of frequent occurrence, and, although I am not at all prepared to admit that under no circumstances is a policy of retaliation justifiable, it is certain that that policy, carried to excess, has at times endangered European peace. There is ample proof that the Tariff war between Russia and Germany in 1893, "was regarded by both responsible parties as likely to lead to a state of things dangerous to the peace of Europe."[65] Professor Dietzel, in his very remarkable and exhaustive work on _Retaliatory Duties_, shows very clearly that the example of Tariff wars is highly contagious. Speaking of the events which occurred in 1902 and subsequent years, he says: "Germany set the bad example.... Russia, Austria-Hungary, Roumania, Switzerland, Portugal, Holland, Servia, followed suit.... An international arming epidemic broke out. Everywhere, indeed, it was said: We are not at all desirous of a Tariff war. We are acting only on the maxim so often proclaimed among us, _Si vis pacem, para bellum_."
