Most people, at a crisis, feel more loyalty to their nation than to their class. This may not always be the case, but there is as yet no sign of any change since 1914, when almost all nominal internationalists became patriotic and bellicose. The class-war, therefore, though it remains a possibility of the distant future, is hardly to be expected while the danger of nationalist wars remain as great as it is at present.
