The second, and far more significant, event was the Tet offensive, so named because it took place during the Vietnamese holiday of Tet, which marked their new year. North Vietnamese and Vietcong forces launched a series of coordinated attacks on American positions all over South Vietnam, including strongholds like Saigon, where even the American embassy was under fire. The attacks were rebuffed and the North Vietnamese and Vietcong sustained heavy casualties, leading President Johnson and our military leaders to claim victory, but in fact, Tet was a huge psychological and political defeat for America, because Americans saw with their own eyes, in our first “television war,” that our forces were vulnerable even in places they controlled. More and more Americans began to question whether we could win a war the South Vietnamese couldn’t win for themselves, and whether it was worth sending even more soldiers into Vietnam when the answer to the first question seemed to be no. On the home front, the Senate majority leader, Mike Mansfield, called for a bombing halt. President Johnson’s secretary of defense, Robert McNamara, and his close advisor Clark Clifford, along with former secretary of state Dean Acheson, told the President it was time to “review” his policy of continuing escalation to achieve a military victory. Dean Rusk continued to support the policy, and the military had asked for 200,000 more troops to pursue it. Racial incidents, some of them violent, continued across the country. Richard Nixon and George Wallace formally declared their candidacies for President. In New Hampshire, McCarthy’s campaign was gathering steam, with hundreds of anti-war students pouring into the state to knock on doors for him. Those who didn’t want to cut their hair and shave worked in the back room of his campaign headquarters stuffing envelopes. Meanwhile, Bobby Kennedy continued to fret about whether he should get in the race too. On March 12, McCarthy got 42 percent of the vote in New Hampshire to 49 percent for LBJ. Though Johnson was a write-in candidate who never came to New Hampshire to campaign, it was a big psychological victory for McCarthy and the anti-war movement. Four days later, Kennedy entered the race, announcing in the same Senate caucus room where his brother John had begun his campaign in 1960. He sought to defuse charges that he was driven by ruthless personal ambition by saying that McCarthy’s campaign had already exposed the deep divisions within the Democratic Party, and he wanted to give the country a new direction. Of course, now he had a new “ruthlessness” problem: he was raining on McCarthy’s parade, after McCarthy had challenged the President when Kennedy wouldn’t.
