A weakness of the study is that it does not look into Gentile populations in the region between Italy and Palestine.
The main issue in Jewish origins is no longer whether they are of Middle Eastern or European (or European-like) origin. It seems pretty clear by now that they are both. The main issue is to determine the origin of their Middle Eastern and European components. This study does offer some new insight by showing the affinity between Jews and Palestinians at K=5 (purple); however the origin of the European (or European-like) component remains elusive.

Genomic microsatellites identify shared Jewish ancestry intermediate between
Middle Eastern and European populations
Naama M Kopelman et al.
Background: Genetic studies have often produced conflicting results on the
question of whether distant Jewish populations in different geographic locations
share greater genetic similarity to each other or instead, to nearby non-Jewish
populations. We perform a genome-wide population-genetic study of Jewish
populations, analyzing 678 autosomal microsatellite loci in 78 individuals from four
Jewish groups together with similar data on 321 individuals from 12 non-Jewish
Middle Eastern and European populations.
Results: We find that the Jewish populations show a high level of genetic similarity
to each other, clustering together in several types of analysis of population structure.
Further, Bayesian clustering, neighbor-joining trees, and multidimensional scaling
place the Jewish populations as intermediate between the non-Jewish Middle
Eastern and European populations.
Conclusion: These results support the view that the Jewish populations largely
share a common Middle Eastern ancestry and that over their history they have
undergone varying degrees of admixture with non-Jewish populations of European
