"我担心我们伟大国家的安全不仅是因为外部的威胁而且是因为从内部作祟的隐秘力量"

Simplified Meaning:

The quote is expressing worry about the safety and stability of a country. The person speaking isn't as worried about dangers coming from outside the country, like other nations or external attacks. Instead, their concern is about harmful forces that exist within the country itself. These internal problems could be things like corruption, division among people, or bad leadership. For example, imagine a family where the parents and children are always arguing. The real issue for the family’s happiness isn’t the strange neighbor causing problems; it's the fighting and mistrust within their own home. Similarly, the health of a nation can be more at risk due to internal conflicts and issues rather than outside threats. To apply this to real life, people should focus on fixing and improving their own communities, relationships, and systems to create a strong, united nation. They need to work together to solve internal problems first to ensure long-lasting safety and harmony.
