Chlorine gas (used on Syrians) depletes the Ozone layer, no Vienna Convention for the militaries? No cancers for them?

Reading about repeated use of chlorine based chemical weapons on Syrians over the weekend I wonder what the global military is doing. I understand they do not give a damn about civilians but do they hear that there is something like the Vienna Convention for the protection of the Ozone layer? Chlor is one of the substances greatly jeopardising its existence and if we do not mind that affected people get their corneas inflamed and can lose their vision as I did or damage their lungs, we should at least think about the cancers, affecting the Earth populations due to the Ozone layers holes. Montreal Protocol control measures clearly state the phasing out of such substances by 2010/2015. We are now in 2018 and as if such international guidelines were non-existent for the military industrial complexes:
