The attack has benefitted both sides in a very cynical way. Netanyahu's reaction has made Israel much more isolated internationally and if any Palestinians make it through all this, they will be even more likely to support a violent and extremist organization like Hamas.
It's a win-win for Netanyahu and Hamas and a huge lose-lose for both Israelis and Palestinians.
Can you imagine having to teach your kids about these risks, help them to deal with them and prepare them for adulthood?
That would be so much work.
