The Bush Administration, with the support of a Democrat-led Congress, is escalating covert military operations intended to de-stabilize Iran's current leadership.
Iran is a Nuclear Non-Proliferation Treaty signatory and has consistently maintained that its nuclear program is intended for civilian purposes only.
The National Intelligence Estimate (NIE) released in December last year, concluded Iran had halted its nuclear weapons program in 2003.
More recently, a May 26th 2008 report prepared by the International Atomic Energy Association (IAEA) criticized parts of Iran's nuclear program. Iranian leadership says the criticism is unfair and asserted the IAEA is being pressured by the U.S.
Don't forget, the U.S. is the only nation ever to have used nuclear weapons on civilians.
