I am pleased to appear before this joint committee to discuss Iran's nuclear program and Iran's imports of sensitive technology. I direct the Wisconsin Project on Nuclear Arms Control, a research organization here in Washington that is devoted to stopping the spread of mass destruction weapons.

I will begin by describing the challenge posed by Iran to the nuclear non-proliferation regime, and then I will comment on some important Iranian procurement attempts. I will conclude with a discussion of Iran's possible noncompliance with its international obligations.
