US or else, I wouldn't trust other governments either, even if you trust governments, your cloud provider could still get hacked and even if it doesn't get hacked you still have to trust a third party: your cloud provider. If you're storing stuff on the cloud, encrypting it on the client first is probably the only way to get (pretty good) privacy.
The only way to ensure your data will not be (easily) extracted is to encrypt it.
I would be surprised if it hasn't already been extracted and added to the governments collection.
Probably slightly safer using a US hosting company. At least some civil rights apply but I don't think there are any rules against the NSA spying on people outside the US.
The story that the CIA sold cocaine is pretty much outside of the realm of conspiracy theories. The idea that spying agencies care about laws is ridiculous. Why should they? If they are doing their job right no one will ever know.
