but I wouldn't be at all surprised if there were or could be cloning operations in places like Russia, China, NK and Saudi Arabia, for example.

Would it not be more likely for it to happen in USAmerica or EU?
Make USAmerica great folk may not have an issue of having cloned soldiers. They seem to be having Nazi saluters too

Regarding EU, less likely to be direct, but could be a partner to USAmerican programmes like how they actively go along for USAmerican invasions
