Commander of the Islamic Revolution Guards Corps (IRGC) Mohammad-Ali Jafari says Iran's enemies keep threatening the country because they have failed to achieve their goals, Press TV reported.
"The enemies of the Islamic Revolution have come to the conclusion that they can not achieve their mischievous goals; therefore they do not abandon threats against the Islamic Republic," said Major General Mohammad Ali Jafari in the city of Shahrekord in western Iran.
The top IRGC commander held Israel responsible for economic conspiracies and sanctions against the country, adding that "the Iranian nation has acquired an all-out readiness against various threats of the enemies of the Islamic Revolution."
Israel is "filled with fear and scared of going into war with Iran," he added.
Commander Jafari's remarks came after a Sunday war threat posed by top US military figure, David Petraeus, who said that Iran could "certainly be bombed" if necessary.
"The level of effect would vary with who it is that carries it out, what ordnance they have, and what capability they can bring to bear," Head of US Central Command said in an interview with CNN.
The United States and Israel say that a military attack against Iran's nuclear facilities is still an option, accusing Tehran of being after nuclear weapons.
Tehran, however, has categorically dismissed the accusations, arguing that all its nuclear activities are peaceful and under the full supervision of the International Atomic Energy Agency.
Iran has warned the US and Israel of a crushing response if they commit the mistake of attacking the country.
The US Office of Naval Intelligence has confirmed in a September assessment that if the United States or Israel decide to bomb Tehran's nuclear sites, Iran's naval modernization and maritime capabilities have reached a point where it can shut down the Strait of Hormuz, through which nearly 40 percent of the world's oil supplies pass.
"Given the importance of the Strait, disrupting traffic flow or even threatening to do so may be an effective tool for Iran," said the intelligence report, citing Iran's domestic accomplishments in seafaring technology.
