Should the smallpox virus be kept or destroyed?

[Bootes Void]

This is an interesting question to ask in light of the Covid Lab leak theory. Right now the Smallpox exists in a lab in Moscow and Atlanta. Should the smallpox be kept around to study? or be destroyed?

There was also a lab explosion in Russia back in September 2019 that was under the radar, so there is a very small but existent risk that it can leak outside the lab.

We have the technology to recreate it if actually needed, so at the very least all samples of the more virulent variola major strain should be destroyed.

Keep for research purposes, but make sure the Chinese never get their own sample of it.

Does anyone know if there's an international treaty/framework establishing standards for the safe handling of potentially dangerous biological samples?  and an actual body empowered to enforce it?  Seems like a good thing to have

     I am curious, what would recreating an extinct virus look like? I am not an expert on virology, but my instinct would be to keep the virus around in case it became necessary to produce fresh vaccine in the future.
