President Barack Obama has defended America's surveillance dragnet to leaders of Russia, Mexico, Brazil, France and Germany, but the international anger over the disclosures shows no signs of abating in the short run.
Longer term, the revelations by former National Security Agency contractor Edward Snowden about NSA tactics that allegedly include tapping the cellphones of as many as 35 world leaders threaten to undermine U.S. foreign policy in a range of areas.
This vacuum-cleaner approach to data collection has rattled allies.
"The magnitude of the eavesdropping is what shocked us," former French Foreign Minister Bernard Kouchner said in a radio interview. "Let's be honest, we eavesdrop too. Everyone is listening to everyone else. But we don't have the same means as the United States, which makes us jealous."
So where in the world isn't the NSA? That's one big question raised by the disclosures. Whether the tapping of allies is a step too far might be moot.
The British ambassador to Lebanon, Tom Fletcher, tweeted this past week: "I work on assumption that 6+ countries tap my phone. Increasingly rare that diplomats say anything sensitive on calls."
Diplomatic relations are built on trust. If America's credibility is in question, the U.S. will find it harder to maintain alliances, influence world opinion and maybe even close trade deals.
Spying among allies is not new.
Madeleine Albright, secretary of state during the Clinton administration, recalled being at the United Nations and having the French ambassador ask her why she said something in a private conversation apparently intercepted by the French.
