[E]arly last month NBC News quoted two senior Obama Administration officials as confirming that the attacks were carried out by M.E.K. units that were financed and trained by Mossad, the Israeli secret service. NBC further quoted the Administration officials as denying any American involvement in the M.E.K. activities. The former senior intelligence official I spoke with seconded the NBC report that the Israelis were working with the M.E.K., adding that the operations benefitted from American intelligence. He said that the targets were not "Einsteins"; "The goal is to affect Iranian psychology and morale," he said, and to "demoralize the whole system--nuclear delivery vehicles, nuclear enrichment facilities, power plants." Attacks have also been carried out on pipelines. He added that the operations are "primarily being done by M.E.K. through liaison with the Israelis, but the United States is now providing the intelligence."
