He has gone to an enemy state without permission which is illegal in itself. The reason he went was to fight in a non governmental force against the government of the country is an offence in Israel and most western countries Doesn't matter what the morality of running off to fight he has broken the law and I hope he is locked up to send a message to others because today they fight against Assad but tomorrow they might be harming Israel by rushing off to war.

He wouldn't be joining IDF,schizofrenic

On the contrary I think Arab Israelis should be encouraged to follow his foot steps. Also they should be provided with condoms in case they encounter virgins up there.
