(TEHRAN, Iran) -- Iranian Supreme Leader Ayatollah Ali Khamenei said the equivalent of "bring it on" Wednesday when discussing threats by the West to impose more economic sanctions on his country if Tehran fails to back down from its nuclear program.
Appearing on state TV, Khamenei practically dared the U.S. and it allies to slap more penalties on Iran.
The ayatollah vowed Iran would "move on our intended path with greater confidence" even as the West threatens "to increase pressures (and) tighten sanctions to force Iranian authorities to reconsider their calculations."
While saying that all options are on the table to get Iran to forgo its nuclear ambitions, President Obama contends that sanctions are the best way to win concessions from Tehran.
However, a series of three rounds of talks between six countries and Iran this year has done little in the way of changing the situation. Meanwhile, the White House is worried that Israel might launch a preemptive military strike to knock out Iran's atomic arsenal.
