Hamas stopped the practise of using children as suicide bombers or militants over 20 years ago so how does that link justify the false imprisonment, torture and starvation of small children.
As your Wikipedia article also states, Hamas leadership made several statements over 20 years ago that child soldiers should never be used. At least one Hamas leader ignored that and said that people are adults from 16 (so kind of akin to the UK) but he died 21 years ago which might account for the lack of recent reports. Completely wrong and abhorrent of the Hamas leaders who did use older children as militants but as the last person doing it died 21 years ago I don’t believe it relates in anyway to the children currently being abused, starved and tortured in Israeli jails.
There have been NO reports of armed children in the current genocide. A huge number of children in prison have not been charged and those that have been charged have mostly been charged with throwing stones at fully grown ARMED adults. Please do not try to justify the imprisonment of children as legitimate on a site for mothers, it is abhorrent. For the record my husband is sporting a gash from a thrown cup by my toddler and I witnessed many kids throwing stones as a child - none were starved, tortured or imprisoned for months!
Israel have been cited as abusing children by using them as human shields and torturing children to get them to agree to be informants for the last few decades!
