Vietnamization was a war policy that was initiated and adopted by President Nixon in Vietnam in 1969 by the U.S to start withdrawing their troops from Vietnam. The withdrawal was necessitated as result of increase reliance in the S.Vietnam Army which lead to U.S withdrawing up to 540,000 of his army from South Vietnam.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.
