So intrusion in government networks and wide interception of the civilian population communication of a countries that are stable, democracies and partners in NATO and allies in the wars US is waging comes as a somewhat hostile stuff.
US is doing too much spying right now. Too wide, too long a period, too broad. Europe has deep scars and trust issues.
In a sense US should abandon SIGINT and stick to the good old fashioned HUMINT with its allies at least. If you want documents and info there are gentler ways to obtain them.
