input: Khmer nationalist Son Ngoc Thanh (1908-77) was a Khmer krom, born in Tra Vinh, Vietnam. Thanh was active in the independence movement for Cambodia. With Japanese support he became the prime minister of Cambodia in March 1945 but was then quickly ousted with the return of the French later that year. Widely supported by the Khmer Krom during the First Indochina War, Thanh's role faded in Vietnam after 1954 as he became more embroiled with politics in Cambodia proper, forming an opposition movement against Prince Sihanouk.  During the Vietnam War and direct American involvement between 1964 and 1974, the Khmer Krom were recruited by the United States Armed Forces to serve in MIKE Force. The force fought on the side of South Vietnam against the Viet Cong but in time the militia regrouped as the "Front for the Struggle of Kampuchea Krom" (French: Front de Lutte du Kampuchea Krom). Headed by a Khmer Krom Buddhist monk, Samouk Sen, the group was nicknamed the "White Scarves" (Khmer: Kangsaing Sar; Vietnamese: Can Sen So) and allied itself with FULRO against South Vietnam. FULRO was an alliance of Khmer Krom, Montagnard, and Cham groups.  The anti-Communist prime minister of the Khmer Republic (1970 - 1975) Lon Nol planned to recapture the Mekong Delta from South Vietnam.  After the Fall of Saigon in 1975 and the Communist take-over of all of Vietnam, the Kampuchea Krom militia found itself embattled with People's Army of Vietnam. Many of the fighters fled to Khmer Rouge-controlled Democratic Kampuchea hoping to find a safe haven to launch their operations inside Vietnam. The "White Scarves" arrived in Kiri Vong District in 1976, making overture to the Khmer Rouge and appealing to the leader Khieu Samphan directly for assistance. The force was disarmed and welcomed initially. Subsequent orders from the Khmer Rouge leadership however had Samouk Sen arrested, taken to Phnom Penh, tortured, and killed. His force of 67 Khmer Krom fighters were all massacred. During the following months, some 2,000 "White Scarves" fighters crossing into Kampuchea were systematically killed by the Khmer Rouge.  In the late 1970s, the Kampuchean Revolutionary Army attacked Vietnam in an attempt to reconquer the areas which were formerly part of the Khmer Empire, but this military adventure was a total disaster and precipitated the invasion of Democratic Kampuchea by the People's Army of Vietnam and subsequent downfall of the Khmer Rouge, with Vietnam occupying Kampuchea.

Answer this question "why were they killed?"
output: During the following months, some 2,000 "White Scarves" fighters crossing into Kampuchea were systematically killed by the Khmer Rouge.

Problem: Background: Mary Kay Bergman was born on June 5, 1961, in Los Angeles. She was the only child of musicians David "Dave" Bergman and Patricia Paris "Pat" McGowan. She grew up around the corner from the home of Adriana Caselotti, the original voice of Snow White. Her parents performed as a singing duo at lounges and clubs in Reno and Las Vegas and in Los Angeles.
Context: Bergman worked on over 400 television commercials, including the voice of Mrs. Butterworth in Mrs. Butterworth's syrup commercials. She had roles in many Disney films, including Beauty and the Beast, as the Bimbettes, The Hunchback of Notre Dame, as Quasimodo's mother, Hercules, as several female characters, Mulan, as the female ancestors, and the posthumously released Toy Story 2, where she provided the yodeling for Joan Cusack's Jessie the Yodeling Cowgirl, as well as the voice of Jessie for the line of Toy Story 2 talking toys and games. Her video games roles included The Curse of Monkey Island and the English version of Tenchu 2: Birth of the Stealth Assassins.  She worked on other series including Jay Jay the Jet Plane, Oh Yeah! Cartoons, The Fairly OddParents, and several female voices in The Tick animated series. She also provided the voice of Gwen Stacy in the final episode of Spider-Man. Bergman voiced the Scooby-Doo character Daphne Blake in Scooby-Doo on Zombie Island (1998), Scooby-Doo! and the Witch's Ghost (1999) and Scooby-Doo and the Alien Invaders (2000), this last one being a posthumous release and final film role, dedicated to her. Bergman's other film role was in Balto II: Wolf Quest (2002) released three years after her death, in which she voiced a vixen and a wolverine.  Bergman contributed vocals to the "Weird Al" Yankovic song "Pretty Fly for a Rabbi", alongside Tress MacNeille. Al stated:  Originally I had Mary Kay come in to sing the whole song. I basically wanted her to do the voice of Kyle's mom from South Park. Her agent wouldn't let her do it (thinking that it might get her in trouble with Comedy Central)--so Mary Kay wound up doing kind of a squeaky voice instead. Later, I decided that the "squeaky voice" thing really wasn't what I was looking for, so I called in my old friend Tress to do her Fran Drescher impersonation instead. The part that you can still hear Mary Kay on is the line in the middle of the song where she does the very Gentile-sounding "for a Rab-bi...".
Question: Did she have any roles in any television shows?
Answer: She worked on other series including Jay Jay the Jet Plane, Oh Yeah! Cartoons, The Fairly OddParents, and several female voices in The Tick animated series.

Question: Sam Houston was the fifth son of Major Samuel Houston and Elizabeth Paxton. Houston's paternal ancestry is often traced to his great-great grandfather Sir John Houston, who built a family estate in Scotland in the late seventeenth century. His second son John Houston emigrated to Ulster, Ireland, during the Ulster plantation period. Under the system of primogeniture, he did not inherit the estate.

Houston was twice elected President of the Republic of Texas. In the 1836 election, he defeated Stephen F. Austin and Henry Smith with a landslide of over 79% of the vote. Houston served from October 22, 1836, to December 10, 1838. The Constitution of the Republic of Texas stated that no president could succeed himself, but did not prohibit any non-consecutive multiple terms.  When his first term ended, he was elected to serve as a representative from San Augustine County in the Republic of Texas House of Representatives. After his term as representative ended, Houston again served as President of the Republic of Texas from December 12, 1841, to December 9, 1844.  While he initially sought annexation by the U.S., Houston dropped that goal during his first term. In his second term, he strove for fiscal prudence and worked to make peace with the various tribes of Native Americans in the Republic. He also struggled to avoid war with Mexico, whose forces invaded twice during 1842. In response to the Regulator-Moderator War of 1844, he sent in Republic militia to put down the feud.  Houston still believed that the U.S annexation of Texas was not a realistic goal and the U.S. Senate would never pass it because of the delicate situation between the recently independent Texas and Mexico. However, Houston was a politician and as such he sought to preserve his career by endorsing the support of annexation into the U.S. Without his endorsement, the Texas congress would have put the question to public election and upon its likely passing would have effectively destroyed Houston's career as a Texas politician. To help save his political reputation, Houston sent James Pinckney Henderson to Washington to help Isaac Van Zandt advocate the annexation of Texas.

Using a quote from the above article, answer the following question: What kind of leader was he?
