Ahmadinejad: 'They know they cannot do a damn thing with sanctions'

Iranian President Mahmoud Ahmadinejad lashed out over the weekend in the wake of Obama signing congressional sanctions into law.

Iranian President Mahmoud Ahmadinejad lashed out over the weekend in the wake of President Barack Obama signing into law last week the toughest-ever sanctions to come out of Congress.

"Bullying powers know that no room will remain for them in the world if the Iranian nation mounts its efforts," Ahmadinejad said, according to the government-owned Press TV. "They know they cannot do a damn thing with sanctions."

The president encouraged a unified effort to counter Western measures taken against the Islamic Republic for its growing nuclear program.

"At any juncture that Iranians were vigilant and united, even the most bullying powers were brought to their knees," Ahmadinejad said.

Obama on Thursday signed the sanctions law, measures in addition to the latest round of U.N. sanctions on Iran. The Senate had approved the bill 99-0, and the House OK'd the unilateral sanctions by 408-8.
