Before we talk about human rights!

When I was a school student, I used to care a lot for the history class specially when talking about United Nations and Human rights,,,, I become very enthusiastic as if she is talking about our dream perfect world but days proved it was really a dream!
Let’s not be pessimistic, no one denies the UN role in many human issues in several countries & different fields,, political one, health & fighting worldwide spreading diseases, defending child & women’s rights.
Am preoccupied these days by the last: women & child’s rights,,, No No am not that kind of women who call for their rights all time with no reasonJ!
Universal statistics states that raping & disusing women & children “sexually” is increasing noticeably through the last 50 years.
Can’t lay the blame unjustly on rapists only,,,, I do imply that for many many reasons… but I feel that we should mainly blame the related laws in advanced countries,, and sure ‘ll blame not enforcing the laws in developing countries where absence of justice is obvious.
The woman/child who lived the experience of rape most often don’t live normal life, she/he becomes psychological patient, we all know Oprah the famous broadcaster,, how she got raped several times by her father’s family and her mother’s family! She was so strong woman… & in her program always hosts people passed through this difficult experience & also professional psychiatrists so they could help them
Please tell me is it enough to send the rapist to jail for minimum 5 years to maximum 20-30 years as a justifying punishment?
What about less developed and developing countries? Where thousands of women & children deal with that experience completely alone… they live with this secret can’t face the society can’t ask for psychiatrist to help them…. they find a way to deal with this experience but unfortunately it’s not the right one.
If they executed the rapists…. They could reach the maximum in establishing justice.
Isn’t one of the UN & human rights different organization’s principles to spread out justice & peace? Or not capable of carrying out the task??
