Who choose not to send us troops despite a bloody civil war because he feared embroiling Americans in another Vietnam?

President Lyndon B. Johnson chose not to send U.S. troops to intervene in the civil war in Laos during the 1960s. He feared that doing so would embroil American forces in another Vietnam-like conflict, which was deeply unpopular and costly. Johnson's decision was influenced by the desire to avoid further escalation of U.S. military involvement in Southeast Asia.
