Yrah no, life doesn't work like that. You're not playing Hearts of Iron. War is horror, death, rape, famine. It's terrible for everyone involved and hurts even those far away from the front lines. "More war." Has not been and will never be the way forward, that is the path that leads back to the stone age.
The fact that you survived growing up a bullied kid with no supports, doesn't mean you came out alright, just saying. Just because greater aggression gives the illusion that it could end war, does not mean it will.
Controls like these don't work if the kid is smart, determined or the parents are too tired or uninvolved. There's more to the cellphone issue than the actual cellphone.
