the concept is this -- people treat you how you treat people
another example would be to go to Vietnam -- we were there to kill them - remember
I don't write as if all readers are 3 year olds who need absolute full explanation -- I expect that people are adults and have some concept of reading comprehension
is it not obvious that where our soldiers have been and disrespected people that we have enemies ---------- whereas where they have been and respected people -------- after wars ------ we have friends
I'm sorry - I cannot see that any intelligent person will have difficulty with any of that
