Negotiations with Iran’s nuclear program needs a scientific component that only an Illinois congressman has.

U.S. Rep. Bill Foster (D-Naperville) said his background as a physicist with a Ph.D in science gives him a unique perspective on the negotiations, which he had plenty of involvement and oversight in technically, which matters a lot in this situation.

Foster said he has been receiving classified briefings on the negotiations to help with some of the technical aspects of the deal, like how to guarantee that even if Iran breaks the agreement, it would take the country at least one year to have a nuclear weapon.

“It’s as important that it’d be as long as possible so that if they do decide to break out of the treaty, or we catch them cheating massively, that we have time to react diplomatically, economically, before we act militarily,” said Foster.

Foster won’t admit whether he supports the agreement because it hasn’t been finalized.

The deadline for reaching a final deal is June 30th.
