West Asia (aka the middle east) is almost a Brazil tier melting pot. All of their greatest empires have faded to dust and the ancient peoples that once existed there (Egypt, Babylon, Assyria, Akkad, Hittites, Persians etc.) have long been bred into the mudpile I'm afraid.
There has been an aDNA revolution. We can compare the genomes of Assyrians, Hitties, Persians, whatever to modern populations. Aryans sadly went extinct, and Northern Scandinavians are the most Aryan-like people.
So that's not true at all (well Islam caused a cultural and genetic decline sadly). Copt Egyptians are very, very close to the ancient egyptians, and modern Egyptians are really not that far off from them. It all worked out in the end, because you can superimpose the west asian genetic clusters over a map of West Asia and see that people settled where they belong. Most Turks literally genetically belong in a region of Turkey. And their geographic neighbours are also their genetic neighbours. It's ancient ancestral composition that matters at the end of the day.
Someone who is 1/2 East Polish and 1/2 English is literally part of the Ethnic German genetic cluster. Oh wow, sans bodies of water, Germany is between England and east Poland. West Poles and East Germans are literally the exact same people.
2/3 Scottish and 1/3 Estonian is part of the Scandinavian genetic cluster. Same logic, although this mix would obviously have a different average genetic quality.
West Asia should scare the shit out of you as to how political and ideological changes can begin to stunlock a region (which started civilization) into the pathetic state it's in now. Israel (Sadly Lebanon could have been developed like Israel but then Palestinian Muslim migration happened) shows what a west asian nation can be like with the right ideology, politics and eugenics (stop fucking your close cousins).
If it was a Brazilian tier melting pot, then the genetic clusters would basically be a huge chunk of Eurasian and African genetic clusters thrown into a small region. But that's not the case. Europeans form a genetic cluster, and West Asians form genetic clusters around the European genetic cluster.
Them being genetically native to a region of West Asia makes Europeans genetically native to a region of Europe. We're interconnected and part of a continnum.
why focus on West Asia if at all?
Because that's the birth place of civilization, neolithic anatolian farmers kick-started the neolithic revolution, and other west eurasians contributed to it. West Asia should not be a shithole, and I don't care if we have to do brutal eugenics on the native populations so they can be on the cutting edge of civilization. Yeet the Abrahamic faith into the trashcan. It's prophesies are just shitty radical political wishes. And Judaism/Islam/Christianity now includes non-West Eurasians when it was intended to really only be used for West Eurasians. So Islam can easily lead to West Asia being invaded by people who are not part of West Asia's genetic cluster.
Besides, we need to get rid of the non-Europeans out of Europe. Having a new nation in the Americas do that would help greatly. Although the death penality would be in place for torturers, murderers and rapist.
West Eurasians are the only people who can take civilization to type 1 and beyond. We've got the shared legacy of innovation to prove it.
West Asians don't belong in Europe, and if that, can only be a very, very small single digit % of the population to have no political, economical or demographic impact. Vice versa.
Israel is an interesting case, as Israel's average genetic profile is very similar to Lebanon's average genetic profile (the Influx of Syrians helped counterbalanced the influx of muslim Arabs). The Mizarahim Jews and Arabs helped adjust Israel's genetic profile to be more in line with Lebanon. The Ashkenazim Jews are a greek-like and south-Italian-like people genetically (different average genetic quality though). They genetically cluster near south italians, some SE europeans, and a few west asian populations.
So Israel is genetically valid as a nation, it fits the levant. A fair and genetically valid arrangement is sending the Palestinians to Jordan. If they can't behave just "turn them off". Plenty of other Levantines and Arabs populations have the Palestinian muslim genetic cluster covered.
