A senior military adviser to Iran's Supreme Leader Ayatollah Ali Khamenei said Tuesday that the United States and Israel are unlikely to launch an attack against Iran, local satellite Press TV reported.

Brigadier General Yahya Rahim Safavi said that "Americans and the Zionists are not in a suitable condition to launch a military attack against Iran," according to the report.

This does not mean that the enemy should be undermined, he said, adding that, on the contrary, Iranians should stand on full alert to defend their territory.

"The enemy should not be underestimated. Wisdom tells Iran's armed forces to be ready ... to fully defend (its territory)," Safavi was quoted as saying.

"Iranian armed forces are in full combat preparation to strongly respond to any probable threat or military assault even beyond their geographic borders," the official IRNA news agency quoted him as saying.

On Monday, Iran's President Mahmoud Ahmadinejad said no military move is possible by the enemies against Iran since enemies are aware of Iran's reaction.

In August, U.S. Chairman of the Joint Chiefs of Staff Mike Mullen said the United States has a plan in place to attack Iran if it is necessary.

"Military actions have been on the table and remain on the table" for curbing Iran's nuclear ambition, Mullen, the highest- ranking U.S. military officer, told NBC's "Meet the Press."
