Iran has long history of dishonesty about nuclear program

Iran has a long history of underhanded diplomacy when it comes to its nuclear program.

For decades, the country has sought to enrich uranium — the key building block to a nuclear weapon — leading to years of effort from the international community to halt the program.

Iran has long insisted its nuclear efforts are for peaceful purposes, but the International Atomic Energy Agency, Western intelligence agencies and others say Tehran had an unchecked weapons program up until 2003.
