New details have emerged about how Israel sought to undermine the Iran nuclear deal—and how the United States sought to stay ahead of the Israeli efforts through intense NSA spying. The Wall Street Journal reports the NSA increased its surveillance of Israeli Prime Minister Benjamin Netanyahu in the months leading up to the talks. The NSA spying showed how Netanyahu leaked details of the U.S.-Iran negotiations, coordinated talking points with Jewish-American groups, and lobbied U.S. lawmakers to oppose the deal. The NSA monitoring of Netanyahu also swept up the contents of U.S. lawmakers’ private conversations, sparking fears in the administration that it would be accused of spying on Congress.
