A prolonged ceasefire between the U.S. and Iran will likely be needed to reach a diplomatic resolution because the parties are so far apart on key issues.

A military operation to remove Iran's uranium stockpile is not a viable project due to the high risk of great casualties.

Iran possesses an estimated 970 pounds of uranium, and the locations of this material are known.

A two-week ceasefire will not be long enough to negotiate a comprehensive deal with Iran; months of negotiations will be required.
