All data is capable of being decrypted somewhere. Usually where you are storing it. Otherwise you can't do anything with it.
Storing data encryped in north korea, with the capability to fetch and decrypt that data in Sweden, is approximately equivalent to storing the unencrypted data in Sweden (as far as hackers, law enforcement, etc. are concerned), except you've now added the additional risk that north korea only needs to exfiltrate one encryption key to gain access to all your data.
More reasonably, if you're storing the data in north korea, that's also where you have the compute, and therefore the decryption keys, and therefore someone in north korea who knows what they are doing can quitely steal the decryption keys, make a copy of your data, and view all the data unencrypted.
Encryption is only foolproof(ish) when you are sending data between two trusted endpoints. That's not the case for the cloud, the place you are storing the data is also almost always one of the "trusted" endpoints. Encrypting the data at rest has some minor benefits (being a hurdle to accessing the data, meaning that theft of a single hard disk doesn't get data) but doesn't provide any form of unbreakable security.
