Nixon promised to end the Vietnam War soon, but Gerald Ford ended it after Nixon was impeached in the Watergate scandel.
Short answer yes, technical answer no. The USA never declared war on North Vietnam, despite fighting there for nearly 10 years. The Vietnam 'war' was started by Kennedy, escalated significantly under Johnson and was still underway when Nixon was elected so Nixon was elected during the Vietnam war. Nixon also successfully ended the Vietnam war on terms which were above and beyond those offered by his political counterparts who werewilling to withdraw unconditionally.

Well, unfortunately, Tricky Dick was Watergated out of office (he resigned) before the war ended. Ford, his vice president was president when the war ended in '75.
