Do you still see Nationalism in today's world? Explain your answer will brainlist

Nationalist ideology continues to shape global politics today, and yet twenty-first-century nationalism is faced with a unique set of challenges. For example, migration and diaspora create cultural, economic and social networks which now bind people across entire continents, let alone countries. The much-discussed onset of globalisation, together with regional integration, has also pushed governments to revise their nation-building rhetoric. Some nation-builders have reacted to globalisation as a potential threat, while others see it as a significant boost to their country’s power and influence. This is important because of the implications for nation-state authority and legitimacy; nation-states seek to square national autonomy with deep involvement in regional alliances, trading networks and international organisations. At the same time, sub-state nationalists continue to compete for people’s loyalty and support. Today, nationalists must reconsider the meaning of self-determination, independence, autonomy and sovereignty in an increasingly interconnected world.
