Things just aren't always what they first appear. Chalabi has more background in playing up to Israel and the Neocons who are most ardently ultra-Zionist than to any probable real intrigue with Iran. Here are two sources that tell another story.
The first is based on the second. The second is more detailed and is written by a researcher from India.

Ahmed Chalabi: The Janos Kadar of Iraq
By B Raman
Selection: After section about why Chalabi fell from grace in Clinton years.
Following this fiasco, the CIA, with Clinton's approval, cut off its funds to Chalabi. Despite this, Chalabi, who had settled down in the UK, remained a frequent visitor to the corridors of power in Washington DC and claimed to have played an active role in encouraging the Congress to enact the Iraq Liberation Act of 1998 calling for a change of regime in Baghdad.
He staged a spectacular come-back into the favours of Washington after the Bush administration came to office in January, 2001. In the 1980s, when he was associated with the Petra Bank in Jordan and before he incurred the displeasure of King Hussein, Chalabi, who was allegedly helping the Mossad, the Israeli external intelligence agency, in the collection of intelligence about Iraq's arms procurements abroad, particularly from the USSR, used to visit Israel secretly.
During those visits, he became close to the late Albert Wohlstetter (he died in 1997), who was reputed to be a godfather of the neoconservative movement in the US, which has a strong influence on the West Asian policies of the present Bush administration.
Chalabi had earlier come into contact with him in his students days at the University of Chicago, but the friendship became close only after their meetings in Israel. Through Wohlstetter, he became acquainted with Richard Perle, who was Under-Secretary of Defence for international-security policy under President Reagan, Dick Cheney and Donald Rumsfeld, both of whom took turns in serving Reagan in his White House Staff.
These friendships stood him in good stead and helped him in his come-back. Perle, as the chief of the Defence Policy Advisory Board, a position which he has since resigned, became a strong supporter of Chalabi, but the CIA and the State Department continued to have serious mental reservations about him.
The CIA was reportedly disinclined to resume funding of Chalabi's INC. It is said that Rumsfeld then ordered that the DIA should take him under its wings and fund the INC.
