The large number of aliens in the United States presents one of the many problems with which the Government has had to deal in the present war. Technically every immigrant from Germany and Austria-Hungary who has not taken out papers of naturalization and who therefor still owes allegiance to the Fatherland is an enemy alien. But while the great majority of these aliens are naturally sympathetic with German war aims, or at least are not ready to give their wholehearted support to the Allies, they are not a source of danger to the United States. Only a small section have given evidence of disaffection, or have tried to cause trouble.
