Against all odds, Iran is pressing hard to prove its nuclear innocence and keeping its promises under the provisions of the Nuclear Non- Proliferation Treaty (NPT). The US is refusing to go along with Iran’s denials on violation of the NPT commitments. At the same time, the Bush Administration seems determined to stop the spread of nuclear weapons beyond Pakistan to other Muslim states. However, the facts emerging out of the probe into the A.Q. Khan episode and the international grey nuclear market indicate significant patterns of concealment and duplicity even by the NPT signatory states.

Washington-Tehran relations have come to occupy centrestage in the recent months given the United States’ current preoccupation with the Middle East. The US-Iran association can be traced back to 1953, when the CIA organised a coup to oust the elected government of Mohammed Mossadeq. Since then, the US has never really disengaged itself from the one of the most strategically important Middle East nations. This paper attempts to identify current US concerns regarding Iran and explores the possibility of a US offensive against Iran similar to that in Iraq.
