It turns out that this is only the tip of the iceberg for the conspiracy theories coming out of the woodwork in the wake of his visit.
Several newspapers published the research of a supposed expert in Jewish studies and Hebrew from Qena University. Faraj Kadri Fakharani seems to say that Ethiopian Jews reached great prominence in their nation in the 19th century and have worked ever since to take over the Nile, one of the most important rivers in the Torah and one of the borders of the Land of Israel mentioned in the Torah.
Fakharani says that Yemen's Jews, who are untainted in their lineage as pure Jews, exported their religion to Abyssinia in modern-day Ethiopia over 2000 years ago. The current Ethiopian leaders, he seems to say, are really Jews who will do anything necessary to wrest control of the holy Nile river from Egypt. The Jewish Ethiopian leaders, we are told, hate Egypt because of their enslaving the Jews in the Hebrew Scripture, as well as saying that God promised the Nile to Abraham but not to Ishmael's descendants, the Arabs.
Oh, and they threaten to block the Nile altogether.
It may sound like a nutty conspiracy theory to you, but a large number of Arabs believe this idiocy.
