The genocidal maniac using misinterpretation intentionally or he's a total fool.

Or both.

The quote comes from the oracle of Balaam in the Torah.

Who's Balaam again?

In some rabbinical interpretations, Amalek is etymologised as am lak, 'a people who lick (blood)'.

Probably had blood in their diet much like the Massai of Africa.

According to the Bible, the Amalekites inhabited the Negev.

They appear to have lived a nomadic or seminomadic lifestyle along the fringes of southern Canaan's agricultural zone.

So any attempts to equate America with Amalek (who was a historic king) is sheer trash, proves some 'semites' can pretend to study all day and come up with wrong answers to support their genocidal agenda.
