Military action in Iran is likely unavoidable, Dick Cheney said on Sunday.
On ABC's 'This Week', host George Stephanopoulous asked Cheney about the effectiveness of diplomatic talks in Iran.
"Is military action against Iran inevitable?" he said.
"I have trouble seeing how we're going to achieve our objective short of that," Cheney said. "And I doubt very much that the diplomacy will be effective if there's not the prospect that, if diplomacy fails, that we will, in fact, resort to military force."
Cheney has long taken a hardline stance against Iran. As Vice President, he repeatedly pushed President Bush to pursue military action. In 2011, he urged President Obama to strike Iran to recover a drone.
