A day after the deadline for the conclusion of negotiations over Iran’s nuclear program expired, the talks continued. Secretary of State John Kerry appears determined to keep talking with his Iranian counterparts in Switzerland as long as it takes to get something signed, no matter how weak or insubstantial in terms of its chances of actually stopping Iran from realizing its nuclear ambitions. If Kerry does succeed in producing a piece of paper that he can call an agreement, the administration will use it as proof that any interference from Congress will be unhelpful to the diplomatic process. But whether he succeeds or not, this week’s spectacle of U.S. officials being played for chumps by the Islamist regime should serve as motivation for the Senate to act when it returns the week after next. Nothing that happens in Lausanne, whether it is endless talks aimed at dragging the West into more concessions or another flimsy interim accord, should be construed as a reason to prevent Congress from voting on measures that require any agreement with Iran to be subjected to an up-or-down vote by the Senate or to pass more sanctions that would go into effect in the event of a breakdown in the talks.
