Almost none of Arabia is in that picture. You don't even know where Arabs are, do you?
Yes, there was some White intrusion in North Africa (which is not the same as Arabia). For example, Morocans are around 10-20% European background, depending on whether they are from south Morocco or north Morocco.
South Moroccan subgroup: 53% North African, 28% West/Central/East African, 11% Southern European, and 10% Arabian
Moroccan subgroup: 50% North African, 18% West/Central/East African, 13% Southern European, 14% Arabian, and 5% West Asian
North Moroccan subgroup: 51% North African, 18% Southern European, 13% Arabian, 8% West/Central/East African and 7% West Asian
That, once again, is a lower % of European descent than the average African-American. Your claim was a lie.
