Iran has ridiculed American threats of war, saying Washington does not have the guts to launch an attack.

The confident Iranian President dared United States to attack Iran.

Iranian leader said that US only makes empty threats against Iran.

"America dare not attack Iran" - said President Ahmadinejad on 24 October 2007.

The firebrand leader of Iran mocked the US military:

"They makes maps of Iran on the wall and only throw darts at it. They make themselves believe that they are attacking Iran. Obviously, they are very angry."

Same day, American Foriegn Secretary admitted that Iran is a too tough for US to handle.

Iran has dismissed sanctions on his country as useless garbage.

Iranian leader has defied US and said that santions against Iran do not have any effect on the country.

Mocking American efforts, President Ahmadinejad said "US sanctions against Iran a worthless pile of paper."

Hardline President said that nothing can stop Iran's nuclear energy drive; and that sanctions hold no values for Iran whatsoever.
