Israel and the U.S. are discussing "red lines" in Iran's nuclear program, that if crossed would justify a preemptive strike on its nuclear facilities. According to the report, Israel's ambassador to the U.S., Michael Oren, filed an official complaint with the administration following a speech by U.S. Secretary of Defense Leon Panetta a few weeks ago, warning against a military strike on Iran. The Daily Beast reported that Panetta's statements infuriated the Israeli government, which ordered ambassador Oren to file the complaint. The White House then relayed a message to Israel saying the administration has its own "red lines" concerning a strike on Iran, and that Israel does not need to act unilaterally.
