It's true that cultural continuity is significant in preserving a society's identity, traditions, and values, which can play an essential role in societal regeneration. However, the relationship between cultural continuity, regeneration, and immigration (or what you term as 'invasion') is not necessarily as straightforward or mutually exclusive as it might seem.

Firstly, cultures are not static but inherently dynamic. They constantly evolve and adapt to changing circumstances, including influences from other cultures. This is not a new phenomenon – cultures have been influencing one another through trade, conquest, and yes, migration, throughout human history.
