The Guardian reports :
One unnamed US official handed over 200 numbers, including those of the 35 world leaders, none of whom is named. These were immediately “tasked” for monitoring by the NSA.
The NSA asked  government agencies to share their Rolodexes, so the NSA would have phone numbers for top foreign political and military leaders.
A confidential government memo admits  that the spying didn’t help prevent terrorism:
The memo acknowledges that eavesdropping on the numbers had produced “little reportable intelligence”.

Because the leaders of allies such as Germany, Brazil, Mexico, the EU and G-20 have no ties to Al Qaeda terrorists, the spying was obviously done for other purposes.
The NSA conducts widespread industrial espionage  on our allies. That has nothing to do with terrorism, either.
Indeed, there is no evidence that mass surveillance has prevented a single terrorist attack . On the contrary, top counter-terror experts say that mass spying actually hurts U.S. counter-terror efforts (more here  and here ).
If NSA spying were really focused on terrorism, our allies and companies wouldn’t be fighting back so hard  against it.
And even the argument that 9/11 changed everything holds no water. Spying  started before 9/11  … andvarious excuses have been used to spy on Americans over the years . Even NSA’s industrial espionage has been going on for many decades . And the NSA was already spying on American Senators more than40 years ago .
Governments who spy on their own population always do it to crush dissent . (Why do you think that the NSA is doing exactly the same thing which King George did to the American colonists … which led to the Revolutionary War ?)
Of course, if even half of what a NSA whistleblower Russel Tice says – that the NSA is spying on – andblackmailing – top American government officials and military officers  (and see this ) – then things are really out of whack.
