This "they stopped using them once they realised the danger" is just about the biggest load of hilarious bollocks I've ever read here, which is saying something.

You are wrong and easily shown to be wrong. Munitions are by definition dangerous, but the specific danger of these to civilians was not at first recognised.
That is why no objection to them was ever made, and no militaries refused them until that danger was made evident.
There was then and only then a campaign against them and decent countries like Britain and Israel stopped using, stockpiling or supplying them.

Jim,
No , because when their danger to civilians was recognised, Israel stopped using and UK stopped selling."
I take it you mean "shelling" -

No. I meant selling.

Gaza remains an untried war crime.

Says who? Only enemies of Israel, gullible one.

They also used chemicals and anti-personnel weapons such as flechette missiles
They used no illegal weapons.

These are serious war criminals comparable to the Assad regime.
Says who? Only enemies of Israel, gullible one, and their record is far worse.
