It is very certain, however, that this outside view of the case enormously underrates the difficulties which stare the politician out of countenance. In matters of this sort it is not so easy a thing to arrive at the truth; much less to state it with such force and clearness that mankind will at once recognise it for truth, and what is said to the contrary for falsehood. The intentions of foreign governments, and the dangers arising out of that quarter, are subjects which it is singularly difficult to discuss frankly, without incurring the very evils which every government seeks to avoid. And if these things are not easy to discuss, it is exceedingly easy for faction or fanatics to misrepresent them.[3] Moreover, the lamentations of the Hebrew prophets bear witness to the {228} deafness and blindness of generations into whom actual experience of the evils foretold had not already burnt the lesson which it was desired to teach. Evils which have never been suffered are hard things to clothe with reality until it is too late, and words, even the most eloquent and persuasive, are but a poor implement for the task. The policy of a nation is determined upon, so as to accord with what it conceives to be its honour, safety, and material interests. In the natural course of events this policy may check, or be checked by, the policy of some other nation. The efforts of diplomacy may be successful in clearing away these obstructions. If so, well and good; but if not, there is nothing left to decide the issue between the two nations but the stern arbitrament of war. Moreover, diplomacy itself is dependent upon armaments in somewhat the same sense as the prosperity of a merchant is dependent upon his credit with his bankers. The news system of the world has undergone a revolution since the days before steam and telegraphs. It is not merely more rapid, but much ampler. The various governments are kept far more fully informed of one another's affairs, and as a consequence the great issues between nations have become clear and sharp. The most crafty and smooth-tongued ambassador can rarely wheedle his opponents into concessions which are contrary to their interests, unless he has something more to rely upon than his own guile and plausibility. Army corps and battle fleets looming in the distance are better persuaders than the subtlest arguments and the deftest flattery.
