This what the disease of nationalism leads to, it's worse than tribalism, with tribalism you have red lines you don't cross, no such thing with nationalism, you will side with the devil to advance your interest.
Once this virulent disease takes hold, the only thing that will cure it is a major calamity, the type that involves persecution, mass slaughter and immense suffering.
Look at Imperial Japan some of the most vicious callous nationalists the world has ever seen, they have butchered millions of people including 3 million Muslims in Indonesia alone and countless atrocities in Korea and China, there nationalism led to suicide operations.
Look at them today, they are known as the most pacifist people in the world, a bunch of feminine looking anime addicts.
Similar story with Nazi Germany, completely pacified and cucked.
They have nationalism (delusional type) we have qabyaalad.
