Does it matter? There's affirmative process for targeting people abroad believed to be involved in terrorism; that is to say: the FVEY IC is practically compelled to target them. It doesn't need permission from any court to do so.

You can argue that the legal protections from housing your data in US jurisdictions is marginal. I won't argue. But you can't argue that your legal protections are worse in the US, because the places you put your data outside of the US have no legal protections at all.

People always misinterpret these arguments as somehow sticking up for the US and the protections it offers residents. No. It's a descriptive argument, not a normative one.
