Lyndon B. Johnson

Step-by-step explanation:

Lyndon Baines Johnson, widely known by his initials LBJ, was the 36th President of the United States of America who took the presidency following the assassination of the previous President John F. Kennedy from 1963 to 1969.

He spent most of his term dealing with the Vietnam War and escalated American involvement in it. By 1964,  he was granted the power to use military force in Southeast Asia without having any permission for an official declaration of war and so 20,000 U.S. troops were sent to the Vietnam.

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
