Is it really that unique? I just looked up the Czech Republic to find that it is 95% Czech[1] but nobody goes around writing articles about whether it is possible to replicate how safe, clean, and functional the Czech Republic is.
Finland also appears to be about 90% Finnish (with 5% Swedish).
Portugal appears to be 95% Portuguese.
South Korea is also over 90%.
Ireland is 85% Irish.
I'm tired of Googling but the more I look, the less I think your point has any validity at all.
Finland and South Korea are absolutely held as a model of civilized society. Very low crime rates, very clean and very orderly. Don't know about Czech but it's possible that being culturally homogeneous is a necessary but insufficient condition, after all I'm sure most of us can name some very homogenous countries that are an absolute nightmare to live in. That said, Dubai and Singapore are also very safe and orderly but they are very culturally diverse, so who knows...
Does anyone know what Australia is like? I hear good things about it, and it is very homogeneous.

Never been there, but Australia has a very low murder rate (0.9 homicide victims per 100k people). But it's also not what I'd call homogeneous, as 30% of residents there were born overseas, higher than the US (14%). Not as much ethnic diversity nationwide, but some of its cities are extremely diverse. 43.2% of Sydney is foreign-born, the 3rd highest percent of any city in the world, with there being Chinese, Indian, Lebanese, Fijian, Korean, Nepalese, Ghanaian and several other communities located inside it.
Canada is another very safe place (murder rate is 2.0 per 100k) and 23% of residents are foreign born. It's also somewhat ethnically diverse as well, with 30.2% of the population being visible minorities. There's also linguistic fractionalization between Quebec and the rest of the country. 49.0% of Toronto is foreign born, the 2nd highest percentage in the world, and Vancouver's not far behind at 42.5% (4th highest in the world).
So Singapore, Australia and Canada are 3 examples of diverse countries with incredibly little violent crime (Singapore actually has slightly less murder per capita than Japan). That's not to say diversity can't result in conflict, but those examples do show that it doesn't have to result in it, and that diverse, peaceful societies can and do exist.
