In foreign policy, Johnson escalated American involvement in the Vietnam War. In 1964, Congress passed the Gulf of Tonkin Resolution, which granted Johnson the power to use military force in Southeast Asia without having to ask for an official declaration of war. The number of American military personnel in Vietnam increased dramatically, from 16,000 advisors in non-combat roles in 1963 to 525,000 in 1967, many in combat roles. American casualties soared and the peace process stagnated. They had two daughters, Lynda Bird, born in 1944, and Luci Baines, born in 1947. Johnson gave his children names with the LBJ initials; his dog was Little Beagle Johnson. His home was the LBJ Ranch; his initials were on his cufflinks, ashtrays, and clothes. During his marriage, Lyndon Johnson had affairs with multiple women, in particular with Alice Marsh (née Glass) who assisted him politically.In 1935, he was appointed head of the Texas National Youth Administration, which enabled him to use the government to create education and job opportunities for young people.
