Why might some Americans during the Vietnam War have found themselves torn between support for and opposition to the war?

Refer below.

Explanation:

Numerous Americans contradicted the war on moral grounds, dismayed by the destruction and viciousness of the war. Others guaranteed the contention was a war against Vietnamese freedom, or an intercession in a remote common war; others contradicted it since they felt it needed clear targets and gave off an impression of being unwinnable.
