Iranian President Mahmoud Ahmadinejad ruled out an attack by Israel against his country over its nuclear activities, saying that the Jewish country is "decaying."

"The Zionist entity is on its way to decay. It is in a very difficult situation, and hopes to revive itself through useless dialogue," the Iranian leader was quoted as telling a press conference in Qatar by the Gulf state's official news agency.

Ahmadinejad arrived earlier Sunday in Doha for talks with Emir Sheikh Hamad bin Khalifa Al Thani.

"This entity cannot do anything, whether in Gaza or South Lebanon, in its favor, or against Iran," QNA news agency quoted Ahmadinejad as saying.

The Iranian leader went further saying that any Israeli military action against his country will lead "to wiping (Israel) from the political geography," the report said.

With regard?to the United States, Ahmadinejad said that there is no signal that Washington is to have a conflict with Iran.

"There will be no war against Iran. All the talk in this regard is only psychological war, and we believe that there are rational men in the United States that who do not support taking such a step," he added.

All threats coming from Israel and the United States are "wishes that are unrealizable in reality," he added.

"Iran is fully ready and is able to hit back crucially against any aggression," Ahmadinejad said.

Qatar is a close ally of the United States which repeatedly expressed deep concerns about Iran's nuclear drive and did not rule out military action against the Persian country.

Western countries and Israel are suspicious that Iran is pursuing a military objective in its nuclear program. Iran denies the allegations, saying it has the right to peaceful nuclear technology as a signatory to the nuclear Non-Proliferation Treaty.
