How did nixon redirect the peace process when he became president

forced Vietnam to the peace table, won treaty concessions from them that protected freedom for South Vietnam, and withdrew our troops with those agreements in place.

No, because after the democrats seized the opportunity to discredit him, and used his political disgrace to renege on the treaties when North Vietnam ignored them and again attacked the South. Millions of deaths can be laid at the door of politically opportunistic democrats.
