It is the business of the naval officer, who is not concerned with party politics, to estimate the posture of international affairs solely in relation to the security of the State. The condition of Ireland at this moment, when the Home Rule issue has been wantonly revived, would, in the event of a war occurring between Great Britain and a foreign Power, involve the necessity of regarding Ireland as a strategic base of essential value, a part of whose inhabitants might combine with the hostile forces by giving them shelter and supplies, and even by inviting them to occupy the country. Elsewhere in these pages, Lord Percy has pointed out that the necessity of holding a disaffected Ireland by garrisoning the country would totally disorganise our military preparations for war--such as they are. These considerations must materially affect strategical dispositions in the event of war, involving the establishment and maintenance of a separate force of cruisers charged with the duty of patrolling the sea routes which converge upon Ireland, and of watching the harbours of her coasts. As matters stand at present, such a force does not exist. It may, of course, be urged that a strategical plan designed for the double purpose of surveying the movements of a hostile battle-fleet and of guarding the trade-routes, must of necessity cover the coasts of Ireland, on the principle that the greater includes the less. The argument, however, omits the essential qualification that a part of the Irish population cannot be trusted. It is this additional difficulty which has been introduced into the problem of naval defence by the revival by politicians of the agitation of 1798, under another name. FOOTNOTES: [Footnote 67: The writer's italics.] [Footnote 68: According to _The Daily Telegraph_ of January 22, 1912.] XI THE MILITARY DISADVANTAGES OF HOME RULE BY THE EARL PERCY The problems of Imperial defence have become of late years extremely complex, owing to the rise of a great European naval power, and also to the predominance of Japan in the Pacific. These two factors, combined with the invention of the Dreadnought type of ship which is now being built by other powers whose navies we could formerly afford to ignore, have rendered our position in the world more precarious, more dependent upon foreign alliances and _ententes_, and have rendered combination for defence far more essential. No Home Rule scheme can be judged without taking into consideration what its effect will be on this situation. It is proposed to consider it first in the light of the more pressing European danger, and next to examine how it will affect the wider problem of the future, namely, the co-operation of all parts of the British Empire for defence.
