Re: Beware the ides of march
The answer is some form of "sovereign cloud", where the Hyperscale-branded cloud is actually located, owned by and operated by a local company under franchise or license. This is exactly why UKCloud (who are a pretty good supplier, all things considered) are now reselling Azure Stack. There are similar arrangements in place with the German flavours of Azure.
AWS and Google are far less good at this. Partially because they don't take the threat seriously and partially because they don't want to provide an entirely hobbled and inconsistent experience under their brand. Azure Stack for example (as being sold by UKCloud) is a far, far inferior product compared to Azure proper in all respects.
