First of a four-part Timewatch reassessment of the life and work of Lyndon Baines Johnson , who took over as US President following the assassination of John F Kennedy in 1963. LBJ will always be remembered for his role in the conflict in Vietnam: he came to power only to see his unprecedented social agenda undermined by a war he supported but never really understood. Beautiful Texas. This first programme examines his ambition and the political instinct which took him from small town rural affairs in Texas via Dallas to the highest office in the United States of America.
