'Nationalism' in Islam

Nationalism is a big topic here (and honestly across the world right now- I think a wave of nationalism is sweeping throughout the world) so I post this as it gives understanding of the issue. This is a short clip which insha'Allah someone might find useful, discussing nationalism from an Islamic perspective and explaining how it should be understood as a Muslim.
Informative. And i would like to ad that the western world are having a surge of nationalistic sentimen. But that same sentiment has always been present in the other continents, and to a more radical one at that.
