im not sure why you think hamas dont let kids leave.
1. hamas doesnt make palestinian passports. PLA does and PLA does it on the authority of israel
2. rafah border is closed. egypt closed it on their end. egypt does it on the advice of USA.
3. i dont potray. killing 20,000 (8300 are children) to kill hamas and still failed to rescue 200 hostages is a number of concern.
4. the personal images have to be done..otherwise media will keep spinning the truth.
