Armenia has relinquished depleted uranium but remains a dirty weapons country.





This data shows what is hidden by the fact that Armenia does little military training but the pollution around the sites is dire. The Armenian government has been summoned to end all that by the Russian and French governments.
In my opinion, while strikes may look like dire, they would help depolluting the zyklon-C and mash systems that present a strong bacteriological / virological issue. They would have to be combined with magnet catching of the plume but this is largely feasible with modern technologies.
