I think that the Pentagon releasing papers ended up simply enraging the people who were anti-war more than they were already upset about. People were already super against the war and were very upset about it than the Pentagon releasing the papers was like the last straw type of deal for many of them.
The release of the Pentagon Papers caused those who were already anti-war to become further enraged. The details in these reports clearly showed Vietnam War opposers why they were against the war in the first place. Had these not become public, the anti-war movement might have not gotten even more steam over this issue.
No, the release of the Pentagon Papers did not cause the end of the Vietnam War, because there was already enough anti-war sentiment that the war was about to end. The Pentagon Papers only added fuel to the fire that was already burning. If people had supported the war, they would have continued to support it despite whatever was in the Pentagon Papers.
The release of the Pentagon Papers did not cause the end of the Vietnam War, it only enraged those who were already anti war. With or without the release of the Pentagon Papers, the Vietnam War would have ended when it did. All it did was make people who were anti war more angry after they got those facts.
The release of the Pentagon Papers didn't cause the end of the Vietnam War. Faulty strategy and a lack of ways to win against guerrilla tactics led to the end of the Vietnam War in 1975. No one expected the conflict to last for such a long time. The Pentagon Papers simply made war protesters mad at President Lyndon Johnson.
