It seems likely, therefore, that neither Great Britain nor any other State will in future enjoy that monopoly of sea power which was granted to Great Britain by the circumstances of her victories in the last great war. What I have called the great prize has in fact ceased to exist, and even if an adversary were to challenge the British navy, the reward of his success would not be a naval supremacy of anything like the kind or extent which peculiar conditions made it possible for Great Britain to enjoy during the nineteenth century. It would be a supremacy limited and reduced by the existence of the new navies that have sprung up.
From these considerations a very important conclusion must be drawn. In the first place, enough victory at sea is in case of war as indispensable to Great Britain as ever, for it remains the fundamental condition of her security, yet its results can hardly in future be as great as they were in the past, and in particular it may perhaps not again enable her to exert upon continental States the same effective pressure which it formerly rendered possible.
In order, therefore, to bring pressure upon a continental adversary, Great Britain is more than ever in need of the co-operation of a continental ally. A navy alone cannot produce the effect which it once did upon the course of a land war, and its success will not suffice to give confidence to the ally. Nothing but an army able to take its part in a continental struggle will, in modern conditions, suffice to make Great Britain the effective ally of a continental State, and in the absence of such an army Great Britain will continue to be, as she is to-day, without continental allies.
A second conclusion is that our people, while straining every nerve in peace to ensure to their navy the best chances of victory in war, must carefully avoid the conception of a dominion of the sea, although, in fact, such a dominion actually existed during a great part of the nineteenth century. The new conditions which have grown up during the past thirty years have made this ideal as much a thing of the past as the medifval conception of a Roman Empire in Europe to whose titular head all kings were subordinate.

DYNAMICS—THE QUESTION OF MIGHT
If there is a chance of a conflict in which Great Britain is to be engaged, her people must take thought in time how they may have on their side both right and might. It is hard to see how otherwise they can expect the contest to be decided in their favour.
As I have said before, in the quarrel you must be in the right and in the fight you must win. The quarrel is the domain of policy, the fight that of strategy or dynamics. Policy and strategy are in reality inextricably interwoven one with another, for right and might resemble, more than is commonly supposed, two aspects of the same thing. But it is convenient in the attempt to understand any complicated subject to examine its aspects separately.
I propose, therefore, in considering the present situation of Great Britain and her relations to the rest of the world, to treat first of the question of force, to assume that a quarrel may arise, and to ascertain what are the conditions in which Great Britain can expect to win, and then to enter into the question of right, in order to find out what light can be thrown upon the necessary aims and methods of British policy by the conclusions which will have been reached as to the use of force.
