"We do not hate you as individuals. But as members of the US military organization, you are unwelcome here. Maybe you imagine you are protecting Okinawa. But because you are here, we never feel safe. Because you are here, we feel constant fear." -Okinawan English blog
After reading this paragraph, if this group think it can promote the idea of kicking US military out, they better think again.
As for my own insights, I think kicking the US military out is probably a last resort measure. As one can observe, they are still currently there, thus there is an agenda of goals we do not know or do know. I believe this is the reason why they have not been kicked out yet.
It also surprises me how this case has become so sensational. Rape is rape whether you're 50 years old or 14. I've heard of rape done to a baby before (search it up in Google's news section). The point is this case has been made sensational beyond what it's suppose to be. If you want to talk about how "shocked" or "appalled" you are of rape done to certain a person of x age then feel free but this is off topic of what a rape case is.
With all due respect, I hope this little girl is well. I hope she did not contract any STD. I also hope she was scolded well enough to understand to be cautious but to also receive the same amount of care and support (I would go with more care and support here because rape can be traumatizing to one's self psychology at this age).
For the soldier, I hope he did not do it in the first place, but if he did, then only justice can be served for him. Innocent until proven guilty.
