"With no prospect of either a military or diplomatic end to the war, the carnage inevitably grew. By late 1967 the number of U.S. military personnel killed in action reached 13,500. Many Americans were wondering if the war was worth the mounting deaths that were so vividly displayed on the nightly news. Slowly, American public opinion turned against the administration. College students in particular became bitter opponents of the war. But the opposition to the conflict also increased in Congress, with Senators William Fulbright (Dem.-Ark.) and Wayne Morse (Rep.-Ore.) leading the attack, bringing to a standstill legislative progress on Johnson's cherished great society program. By 1967 growing demonstrations against the war and vicious personal criticism of the president had made Johnson a virtual prisoner in the White House. The increasing unpopularity of the war, however, did not sway Johnson from his goal of preserving a noncommunist South Vietnam. For the president in 1967, there was no acceptable alternative but a continuation of the war. Accordingly, in August 1967 he approved General Westmoreland's request for an additional 45,000-50,000 troops, but he imposed a new ceiling of 525,000 military personnel, a level that was not surpassed for the remainder of the war. In November 1967 Westmoreland assured Johnson that the United States was "turning the corner" in Vietnam."
