What we get is culture clash, where people are essentially born with different values, customs, and ways to behave in society.
There is very good internet lore, which sort of describes this phenomenon called "The Eternal September":

What Europe is experiencing right now, is essentially the same as what the internet experienced during Eternal September; the ability and capacity to assimilate has been exceeded, and therefore yes, there is a very real possibility of destruction of the western culture and values.
As for stopping the bombing and destruction of these countries, you simply cannot argue with that proposition.
It's actually quite perplexing that politicians are putting so little effort into solving the root cause, instead preferring the virtue signalling easy route, without seemingly any thought to the actual cultural and societal consequences of their actions.
