>Conducting any form of surveillance without a warrant (the constitution doesn't talk about citizens) is illegal. The Supreme Court has ruled before that the constitution only partially applies to places where the US has jurisdiction but in which it is not a state (see the Insular Cases). Imagine a place where the US has no jurisdiction at all! Boumediene v. Bush (2008) seems to slightly reverse this idea (people in Guantanamo Bay have constitutional rights!) Maybe the best course of action is to invite Merkel to file suit against the NSA. There's well documented facts of warrantless wiretapping of her phone.
