Nearly all are “countries” solely as legacies of European colonial rule with borders drawn up on maps in wood paneled rooms thousands of miles away. They were happily spearing and chopping each other to bits before the pale strangers arrived and in most cases have or will revert to tribal slaughter and caste and once they’ve left. Some which were unified and functioning like nation states before the Europeans arrived and avoided being colonized (China, Thailand, and Japan for example) are doing rather well.
Not only that, but Europeans decided that wasn't even killing and decided to spread marxisim and communism around the world. The black book of communism is littered with examples of death and destruction from those influences. Praise be to European ideals!
Even now, whitey as a individual is much better at killing than inner city youth. White men almost always have a higher body count per try than most in killing sprees. Merit matters. Cheers!
