Bloomberg: Chancellor Angela Merkel has little to show for an effort begun a year ago to limit American spying in Germany as talks between the two countries on U.S. surveillance have run aground.

Meant to calm German outrage over alleged American espionage, the negotiations have been further hampered by the latest reports in Germany that the country’s BND foreign-intelligence agency collaborated with the National Security Agency to help the U.S. spy on European allies and companies, said a person familiar with the matter, who asked not to be identified discussing sensitive talks.
