Ignoring the Albanian trolling, it does seem that Iberians (perhaps except Basques) have some post-Neolithic "Near Eastern" (i.e. Iran/Caucasus-heavy) ancestry compared to the Bronze Age Iberian samples which I suppose might have arrived with any number of peoples there after the Bronze Age. Of course, as pointed out and is noticeable on the PCA cline too, it's much lower than in the Balkans (even the ancient Balkans) where it seems to have been present since the Bronze Age (see the already well-analyzed Mycenaean samples and the ADMIXTURE runs of the still unpublished samples in the Mathieson paper) and seems it might have increased a bit too since then. Also, as you said, ties between Iberia and North Africa are old as well and even mtDNA L was found in ancient Iberia (I forget the sample though).
Lolno, the Minoans already had a decent amount of this type of ancestry and modern Cretans have even more - and trust me, it's not due to post-Lausanne immigrants. Similarly the vast majority of those 'recent refugees' were Greek mainlanders and islanders, as I've already pointed out to you, so a lot of them had much less 'near eastern' ancestry than Cretans do. Cretans are basically one step removed from Cypriots genetically, and they similarly received the Greek language from the mainland in the Bronze Age. You'll have to deal with this at some point.
