Delicately put, it’s due to their racial and cultural homogeneity.
Nailed it.
Yes their culture is intact
But no the left and NEOCONS and even victor Davis the Hanson crew about how race and ethnic homogeneous variables are not important in creating a nation
What bullshit
It’s why the Japanese preserve theirs
Admixture to the founding group means slow as she goes or a little goes a long ways
So thanks elected leaders for everything
