100 THE BRITISH APPROACH TO POLITICS, First, that it may lead to militarism—i.e., the belief that war is the only way of settling disputes, and that the country exists for the sake of the Armed Forces, not the Armed Forces for the country. Second, it may actually weaken the efficiency of the Forces. Their whole training encourages the habit of obedience, and of accepting things as they are; after years of such training it is not easy to keep the mind open to new ideas. The reluctance of the Navy to realise the importance of the submarine, and the slowness with which the Army adopted the idea of the tank, are illustrations. In all three Forces, the officers are drawn from one class, the men from another. Promotion from the ranks does occur, but it is not the rule. The dangers of this to liberty have already been noticed; there may be the further result that the grievances of the ordinary soldier and sailor about pay and conditions will not be fully understood by those in command. The mutiny at Invergordon, in 1931, when cuts in pay were proposed, might never have occurred if the Board of Admiralty had realised what the proposals would mean to the men. It is an unfortunate fact that Governments have usually been induced to make improve- ments in naval life by the fear of mutiny. Recent improvements in Army conditions have also been caused by the impossibility of getting sufficient recruits without them. All the Armed Forces are recruited voluntarily; the system of compulsory military service, so common on the Continent, has never been used here except in wartime. The old dread of increasing the power of the Crown, and the natural objection of citizens to compulsion, have made the idea of conscription unpopular. If military discipline turns citizens into people who will always do what they are told, and regard war as a permanent habit of mankind, no lover of peace or liberty can approve conscription. On the other hand, if all citizens have some military training, the danger of a seizure of power by the Armed Forces is much less. Finally, there is the problem of co-ordination of the
