I can understand why "world leaders" would be frustrated by this, but much better them than us. This activity is at least plausibly within NSA's purview. Also, <i>most</i> of these leaders have less at risk to the NSA threat than do USA residents. It isn't as though NSA will sic the Drug Warriors, the IP Mafia, BATF, ICE, or EPA on leaders of other sovereign nations based on its observation of their communications. Whereas we're definitely in those crosshairs.<p>There are exceptions! If your nation could plausibly be on deck for the next military-industrial complex fundraising activity, you might want your leaders to secure their communications against NSA. Of course, if they're not doing anything wrong, they might want that fact to be observed, on the off chance it might make a difference.
