explain america's views toward the vietnam war from the 1940s through 1968.

America's view in the Vietnam was fear. Fear drove them to participate in the war. Why fear? They were afraid Vietnam would become communist because if they became communist they would support or have the support from the Soviets. If this were to happen Vietnam could've became a missile launching spot for the soviets if America wouldn't have participated.

It's my best explanation from what I remember and from what I think. Hope it's helpful to you.
