An Iranian top official warned the United States on Tuesday to beware of the possible results if it launch a military action against the Islamic Republic, the semi-official ISNA news agency reported.
If the United States attacks Iran, they may face three problems: they can not predict "the volume of our response"; they don't know what would happen to Israel and Washington will not know what will the oil flow look like at that time, General Rahim Yahya Safavi was quoted as saying.
Safavi stepped down last week as chief of the elite Revolutionary Guards and now serves as senior military advisor to Iran's Supreme Leader Ali Khamenei.
He made the remarks just days after the U.S. President George W. Bush said Iran's continued nuclear program may lead to a "nuclear holocaust" in the Middle East.
The United States has never ruled out the possibility to launch a military attack against Tehran's nuclear facilities.
A Western media recently reported the United States had made a plan to destroy Iran's military capability in three days if Tehran doesn't comply, drawing great attentions from the international community.
Iran has repeatedly vowed to fight back any outside aggression. After years of development, Iranian forces now has the Shahab-3 missile which could cover Israel and U.S. bases on the Arabian Peninsula with a range of 2,000 km.
Tehran also has threatened to block the Strait of Hormuz, a vital channel for the transport of the region's oil to the world.
