Israel are not colonizers though. Israel is one of the indigenous people finally returning to their homeland. You can say they should share and I agree but the immediate attempt at their annihilation right when they were established definitely indicated that many of their neighbors were not keen on sharing nicely. It's awful that the children in Gaza are suffering but the blame for that lies with the terrorists who use those children as human shields, tore down the infrastructure, and diverted construction materials meant for humanitarian aid to be used to enable further terrorist attacks, not the country that forced it's own citizens out and left a fully functioning set of infrastructure for the new inhabitants.

Edit- I was hoping to get away from Reddit culture of disagree=downvote and was looking forward to productive respectful discussions here. So far it seems not to be working out but maybe we can still turn it around
