Vietnam: Republican stopped Negotiations and 22,000 US soldiers died.

Liberals Unite covered this story last July. To recap that article, the Smithsonian reported that:

In 1968, the Paris Peace talks, intended to put an end to the 13-year-long Vietnam War, failed because an aide working for then-Presidential candidate Richard Nixon convinced the South Vietnamese to walk away from the dealings, says a new report by the BBC’s David Taylor. By the late 1960s Americans had been involved in the Vietnam War for nearly a decade, and the ongoing conflict was an incredibly contentious issue, says PBS.

Nixon was campaigning for president in ’68 on a platform that opposed the war and needed the war to continue. As BBC reports,

Nixon feared a breakthrough at the Paris Peace talks designed to find a negotiated settlement to the Vietnam war, and he knew this would derail his campaign. […] In late October 1968 there were major concessions from Hanoi which promised to allow meaningful talks to get underway in Paris – concessions that would justify Johnson calling for a complete bombing halt of North Vietnam. This was exactly what Nixon feared.

Nixon went on to win the election by a narrow margin, and as BBC reports:

Once in office he escalated the war into Laos and Cambodia, with the loss of an additional 22,000 American lives – quite apart from the lives of the Laotians, Cambodians and Vietnamese caught up in the new offensives – before finally settling for a peace agreement in 1973 that was within grasp in 1968.
