As a European I do indeed find this troubling. I know that "everyone does this", and "this is how it's always been", but morally speaking whether a person is a citizen of one country or another has no impact on whether it is justified to spy on them. As a collective society humanity has to grow up and leave this stuff behind. Fundamentally these problems trace back to the nation state, which itself is an inherently discriminatory instrument. It assigns special privileges to people based on where they were born. If we as a species believe that everyone should have access to equal rights and equal opportunities, then there can be no international borders arbitarily cutting up the landscape of rights and opportunities. The nation state was a tool that was useful in humanity's adolescence, but we have to leave it behind if we ever want to grow up. Not that any of that is easy, but just because something is hard doesn't mean it isn't necessary.
