Gassing would make it much harder for Israel's Hasbara propagandists to sell the genocide to the West.

Luckily chemical and especially biological weapons are hard to use without risk of collateral damage. Like with any chemical reaction, dilution is generally the solution, and there's a whole bunch of air moving around.

Plus most of the really effective gasses are horrific blistering agents, and I hope to think even the west would balk at seeing the results of that being done to children. But, that may be me being optimistic.
