Efforts to end the war in Vietnam and return veterans to U.S. soil continued through the 1970s. Richard Nixon had won the 1968 election on his campaign promise to end the war, though he was helped by the opposing party's disarray. As the years passed, President Nixon became increasingly paranoid. He resented the antiwar movement, and he used his power and influence to intimidate those he saw as enemies. As time wore on, his list of enemies seemed to grow substantially larger.
