No one is going to stop development for fear the other will have the advantage.
For controls on this to work, there would have to be a treaty governing development among the big nuclear powers —then they with their big sticks dictate the rules to the rest.
In the vacuum of that everyone will feel they have to develop or get left behind.
Additionally something like this (the enabling of political “decapitations”) is only seriously countered by MAD. So nothing would keep Colombia from developing their own and taking out Maduro for example if they were reasonably sure a better alternative would rise in VZ.
Not the big nuclear powers — they should be relatively easy to get onboard, because preventing proliferation of nuclear weapons is comparatively easy compared to preventing proliferation of drones. The ones to watch are the smaller countries who have in effect lost their sovereignty to the nuclear powers: maybe Colombia, but also Taiwan, Canada, Ukraine, Spain, Brazil, Iran, the UAE, Egypt, Bangladesh.
More worryingly: Daesh, Baruch Goldstein's fan club, the next Anders Breivik, the janjaweed, Boko Haram, Voluntad Popular, antifa groups, the collectively fired Minneapolis Police Department, the Hells Angels, MS-13, etc.
I agree there, except for the domestic organizations. They could develop crude drones but not the hypersonic loitering kind —I’m not even sure they’d need that. Hypersonics only make sense when you need to penetrate stiff air defenses and get to destination to neutralize the big armament from reaching altitude.
They could be used by the US, Russia, China, India, Pak, Israel to “decapitate” “rouge” regimes incapable of retribution.
Mexican and ukranian drug orgs? maybe crude non hypersonic for whatever political purpose.
Or imagine the ndraghetta having the crude variety during the time they tried offing magistrates quicker than the state was able to convict the perps... or the Italian red brigades...
Agreed, it would be surprising if the Zetas were able to develop hypersonic drones. But I don't think the hypersonic part is vital to their political assassination capacities.
