"There are, for example, Trotskyists who have become simply enemies of the U.S.S.R. without developing a corresponding loyalty to any other unit. When one grasps the implications of this, the nature of what I mean by nationalism becomes a good deal clearer. A nationalist is one who thinks solely, or mainly, in terms of competitive prestige. He may be a positive or a negative nationalist—that is, he may use his mental energy either in boosting or in denigrating—but at any rate his thoughts always turn on victories, defeats, triumphs and humiliations. He sees history, especially contemporary history, as the endless rise and decline of great power units and every event that happens seems to him a demonstration that his own side is on the upgrade and some hated rival is on the downgrade. But finally, it is important not to confuse nationalism with mere worship of success. The nationalist does not go on the principle of simply ganging up with the strongest side. On the contrary, having picked his side, he persuades himself that it is the strongest and is able to stick to his belief even when the facts are overwhelmingly against him."
-George Orwell

There was a time when this group of immigrants came to a union of nations and they raped, murdered, brought horrible diseases that killed 95% of them, and spread their religion. You might've heard of them.
