Opinion on the Vietnam war

I I do not really know why we went to Vietnam. I was told to help fight communism. They told me that this war would prevent bad people from taking over other people that cant defend themselves. But anyway I did not really like it. Every time we went into town we were called heroes and received gifts. But in the back of my mind I was scared. I was scared because the little kids would hit grenades in fruit baskets and blow  themselves up. I always had my m16a1 on full auto just in case one these sneaky little kids try to blow me up with a fruit basket. This war was very brutal and unforgiving. I did have alot of respect for them knowing they have the home turf advantage I was happy when i got home. I got tired of looking up all the time looking for snipers.
