The US intelligence establishment must have been very confident that their surveillance methods would never be discovered by the surveilled individuals in order to risk wiretapping European leaders. Otherwise, it is difficult to understand how on earth they decided to gamble those relationships with some of their closest European allies in exchange for information obtained from phone conversations of Hollande, Sarkozy, Chirac or, as revealed some time ago, Merkel. They calculated wrong. Obviously they didn’t see Wikileaks coming—maybe they are not that intelligent after all. (see US Spying, a very wrong calculation)
