Shipwrecked Faith Deuteronomy 28 Trans-Atlantic Slave Trade or A.D. 70?

Is there any Bible justification for the following claims of the Black Hebrew Israelites?

• America is Egypt
• Deuteronomy prophesied the Trans-Atlantic Slave Trade
• A future regathering of Israel

A methodical dismantling of the Hebrew Israelite interpretations of Deuteronomy 28 and their claim that it supports the a scattering of Israel in A.D. 70 with an ongoing regathering at the return of Christ.
