How would you describe the course of the war between 1965 and 1968?

Between 1965 and 1968, the Vietnam War escalated significantly, marked by increased U.S. military involvement following the Gulf of Tonkin Resolution. The U.S. deployed combat troops, leading to intense ground battles and airstrikes against North Vietnamese forces and the Viet Cong. The conflict's intensity peaked during the Tet Offensive in early 1968, where a coordinated series of attacks by North Vietnamese forces challenged U.S. perceptions of victory, ultimately shifting public opinion and leading to a growing anti-war movement in the United States.
