Answer:
D) allowing Vietnam to reunify under a democratically-elected government
Explanation:
According to the quote from a speech given by President Richard Nixon on November 3, 1969, he talked about the previous administration and how they Americanised the war and his plan to Vietnamise it.
The change in policy that President Nixon was promising to make in this speech was allowing Vietnam to reunify under a democratically-elected government.
Vietnamization is a term used to describe the policy of Richard Nixon to significantly end the US involvement in the Vietnam War by training and equipping South Vietnamese soldiers to fight the war.
The reason that they were was because of FDR famously holding four terms in office, presumably because it would be a poor example for a democratic nation to have a single elected leader for such a long period of time. There are probably multiple arguments both for and against allowing multiple terms in office, however.
One reason why the people of Russia looked to boris yeltsin for leadership instead of to mikhail gorbachev in late 1991 is because it was clear by this point that the Soviet Union had ended, and they wanted someone more willing to form ties with the west.
