The correct answer is D) U.S. citizens were concern about the loss of soldiers and civilians in the war.
An anti-war movement developed in the United States while President Johnson escalated the war in North Vietnam because U.S. citizens were concern about the loss of soldiers and civilians in the war.
United States citizens were watching the news reports about the Vietnam War and realized that America was not winning the war, many young American soldiers were dying as well as civilian people in Vietnam. So they began to question the reason why the U.S. was fighting a war that really didn't belong to them. As a result of this, many people took the streets and organized marches to protest against the war effort. So yes, U.S. citizens were concern about the loss of soldiers and civilians in the war.
