The Israelis cannot help themselves. They will stop at nothing to torpedo any chance of a US-Iran rapprochement, up to and including disseminating such fantastic tales. Ultimate irony is Israel's declaration that Iran's sending an official to collect intelligence against US is per se sign of hostility. If that were the test than consider US and Israel at war since 1948. Nice try, the decision to re-engage was made unilaterally at the highest levels of US government, and with only the appearance of Israeli input and consultation.
