Migration crises are really important and affect how countries keep themselves safe. Here’s how these situations change national security policies around the world:

1. More Border Security

• Tighter Border Control: When a lot of people move into a country, that country often spends more money on border security. For instance, in 2020, the European Union spent around €800 million to improve its border safety.
• Military Support: Countries like the U.S. and Italy have sent military forces to help protect their borders because they feel more worried about security.

2. Changes in Policies

• New Laws: Crises with migration often lead to stricter immigration rules. After the Syrian refugee crisis in 2015, many European countries made it harder for people to get asylum, which led to a 20% drop in applications in 2016.
• Nationalism vs. Globalism: As more people migrate, some countries start to focus more on their own needs rather than helping others. This can change how they handle agreements to take in refugees.

3. Effects on Society

• Public Opinions and Safety: A survey from Pew Research in 2018 showed that 67% of people in several European countries see immigration as a threat to their national security.
• Increased Extremism: Challenges from migration can also lead to a rise in home-grown terrorism. Studies have suggested that more migration can cause far-right groups to gain power, which can hurt social stability.

4. Working Together

• Teamwork on Security: Countries are starting to work together more. They make agreements to manage migration. A good example is the EU-Turkey deal from 2016, which aimed to limit irregular migration to Europe by sending migrants back to Turkey in return for financial help.

Conclusion

In short, migration crises cause big changes in how countries think about safety. Nations are building stronger borders, creating new laws, and finding ways to work together to handle security and help people in need, especially as public concerns grow.
