(JNS.org) Israel must be prepared to act alone in the face of the Iranian nuclear threat, Maj. Gen. (res.) Yaakov Amidror, an adviser to Prime Minister Benjamin Netanyahu and the former head of the Israeli National Security Council, said Sunday at the annual Herzliya Conference.

"While the U.S. is an irreplaceable strategic ally, we need to be ready to do things on our own," Amidror said, according to Israel Hayom.

In response, U.S. Ambassador to Israel Dan Shapiro said the U.S. "will use military force if necessary."

"Not every problem results in military action," he said.
