Answer:
The best option is letter A) felt their efforts were not successful.
Explanation:
The excerpt we are analyzing here was taken from a memoir called "A Rumor of War" by Philip Caputo. Caputo recalls his experience at the Vietnam War and how he believes America's involvement in it was all for nothing.
As we can tell from the excerpt, soldiers did not seem well prepared at first. They misjudged their enemy, thinking of them as mere "peasant guerrillas". The enemies turned out to be lethal, and more and more American soldiers died each week. That "broke [their] confidence", which means they felt their efforts were not successful. In the book, the author even says he wishes he had different war stories to tell instead of the ones he actually lived. Battles in Vietnam were exhausting and never-ending; the enemy was seemingly undefeatable, hiding in jungles filled with traps and snipers.
Frist logical connection between the two is that Manzanar Internment and the Japanese living in West Coast of USA are both Japanese people forced to live in isolation because American government thought that Japanese had invaded Pearl Harbour and they must be looked upon with suspicion.
Secondly,in both the cases ,innocent Japanese may have suffered isolation because"Fear was Stronger than Justice".American government was not ready to listen to Japanese people living in USA whether they were innocent or not.They could be potential spy ,ready and willing to assist Japanese in invasion.
