"The United States is showing off by threatening to use its wild dog, Israel," the public relations head of the Revolutionary Guards, Commander Seyed Masood Jazayeri, was quoted as saying by the Iranian student news agency
"They will not hesitate to strike Iran if they are capable of it. However, their threats to attack Irans nuclear facilities cannot be realised. They are aware Tehrans reaction will be so harsh that Israel will be wiped off the face of the earth and US interests will be easily damaged," he warned.
The commander asserted that Iran would not initiate a conflict, but in retaliation to any attack has proved itself to be "harsh, assertive, hard-hitting and destructive."
Iran's controversial bid to generate nuclear power is seen by arch-enemies Israel and the United States as a cover for nuclear weapons development, allegations that Iran denies.
