TEHRAN, Iran -- American proposals for direct talks with Iran are pointless while Washington is "holding a gun" to the country through sanctions, Iran's supreme leader said yesterday, quashing a possible breakthrough in contacts with the West over the nuclear standoff.
Their dismissal of one-on-one dialogue raises the stakes when wider negotiations between Iran and world powers, including the United States, resume this month.
Another dead-end round, after three stalemated sessions last year, could fuel accusations by Israel and others that Iran is using the talks as a stalling tactic while it gets closer to having the capabilities to build a nuclear weapon.
Israeli Prime Minister Benjamin Netanyahu has warned that the world has until this summer, at the latest, to keep Iran from building a bomb. He's hinted that Israel could attack unilaterally if all other efforts fail. Iran denies it seeks atomic arms.
"Talks are held to arrive at an understanding, not to impose anything," Ahmadinejad said. "Such talks will be meaningless if someone raises a club and imposes" something on Iran, he added. Talks would be productive only if they were based on mutual respect, he said. "Things will be fine if the Americans correct the manner in which they address us."
The earlier comments by Khamenei were his first public reaction since a White House offer of direct dialogue received a high-profile boost this week from Vice President Joe Biden during a security summit in Munich attended by Iran's foreign minister.
"Talks will not solve any problems," Khamenei said in comments posted on his website. "The Iranian nation will not be frightened by such threats," he added in a reference to U.S. sanctions over Iran's nuclear efforts.
This week the United States further tightened sanctions, which have already slashed Iran's oil revenue by 45 percent. The new measures seek to cut deeper into Iran's ability to get oil revenue, calling on countries that buy Iranian crude -- mostly Asian nations including China and India -- not to transfer money directly to Iran and instead place it in local accounts.
Yesterday's comments followed another jab at the United States: This week Iran's state TV broadcast a video allegedly extracted from a CIA spy drone captured in December 2011 after crossing into Iranian airspace. Iran has long claimed it managed to reverse-engineer the RQ-170 Sentinel, and that it's now capable of launching its own production line.
