Apparently they can be even up to a dozen or so percent Polish:

What I'd like to see is a study comparing modern AJ to the ancient Bronze Age Canaanite genomes analyzed in Haber et al 2017. Then we can really look at how much of their ancestry traces back to post Neolithic west Asians and how much is European admixture.
Haber et al. modeled the Sidon_BA samples as Levant_N + Iran_Chl, this is what Ashkenazi Jews get if I use K7:
[1] "distance%=0.2834 / distance=0.002834"
Ashkenazi_Jew:average
Levant_Neolithic:I1704 38.50
Italian_Tuscan:average 25.70
Iran_Chalcolithic:average 19.70
Polish:average 13.35
Lithuanian:average 2.75
A very good fit, which is in line with Ashkenazim being 55% to 60% Levantine in origin on average (usually around 57%).
Very neat! A little more Polish/Lithuanian than I had anticipated.
If you've got Sephardi and other Jewish groups as well, I'm curious to see how they'd compare.
I suspect the Eastern European is inflated by a factor of ~2 here. Anyway, this is what Sephardim get:
[1] "distance%=0.175 / distance=0.00175"
Sephardic_Jew:average
Levant_Neolithic:I1704 36.70
Italian_Tuscan:average 24.30
Iran_Chalcolithic:average 20.10
Italian_Bergamo:average 10.85
Spanish:average 6.35
Avar:average 1.70
Avar should be added to Levant_N and Iran_Chl, in many cases it improves the fit (my father is a pretty good example of this actually). All in all they're extremely similar to Ashkenazim (they're basically a single population anyway, but you won't see Elhaik saying it).
This is what Mizrahi Jews get:
[1] "distance%=0.1952 / distance=0.001952"
Iraqi_Jew:average
Assyrian:average 43.15
Levant_Neolithic:I1704 28.70
Iran_Chalcolithic:average 26.70
Avar:average 1.45
[1] "distance%=0.1909 / distance=0.001909"
Iranian_Jew:average
Assyrian:average 41.4
Iran_Chalcolithic:average 31.6
Levant_Neolithic:I1704 24.9
Iranian_Zoroastrian:average 2.1
Mizrahi Jews are by and large of Mesopotamian origin, so it's extremely likely Iran_Chl comprises some of their Mesopotamian ancestry. Samaritans are likely to be the closest contemporary population to Sidon_BA, so they're probably a better proxy for actual Judean ancestry in their case:
[1] "distance%=0.1369 / distance=0.001369"
Iraqi_Jew:average
Assyrian:average 47.05
Samaritan 39.30
Iran_Chalcolithic:average 9.85
Avar:average 3.80
[1] "distance%=0.1115 / distance=0.001115"
Iranian_Jew:average
Assyrian:average 39.95
Samaritan 36.65
Iran_Chalcolithic:average 18.45
Avar:average 4.00
Iranian_Zoroastrian:average 0.95
^^These fits make much more sense, they're in line with what Mizrahim usually get, like I said they're basically a Mesopotamian population. As incredible as it might sound, Western Jews (Ashkenazi, Sephardic, Italian, Romaniote, North African, Syrian, Egyptian, etc) seem to have inherited larger chunks of Israelite/Judean ancestry (between 55% and 60% on average) than them. Based on the above, I also think it's safe to conclude that the Assyrians are going to be very similar to their ancient namesake.
