A serious compromise needs to be put on the table, including an offer to suspend crippling oil sanctions in return for specific, verifiable Iranian steps to eliminate any nuclear breakout capabilities. Equally significant is establishing a credible military threat, given that Tehran has been willing to endure increasing economic pressure in order to continue its nuclear program.

In the same vein, the military option requires a credible negotiating complement, as seen in the early 1990s with Iraq. To legitimize military action against Saddam Hussein's regime, Washington had to prove that all other options had been exhausted. Similarly, the only way to set the predicate for military action against Iran is to show the regime and the international community that everything has been tried, and that Washington has left Tehran with a way out.
