Iran Races to Enrich Uranium for . . . What, Exactly?

Hot Air points to a Guardian article in which the author asks why Iran is rushing to enrich nuclear fuel:

[T]here is another huge question mark hanging over Isfahan and Natanz: why is the government in such a rush to enrich fuel, when it has no nuclear power plants in which to use it?

This race to make enriched uranium stands in stark contrast to Iran's complacency over its nuclear power plant, which has been stalled due to Iran's failure to pay Russia's RosAtom $100 million. The plant is supposedly only months from completion, but Iran won't pay the money it owes. In mid-July I said:

I see three possible scenarios: 1) Iran doesn’t have the cash (unlikely - $100 million is nothing); 2) Iran wants to use the plant as a bargaining chip and has no interest in dumping more money into something they’re just going to trade away; or 3) Iran never wanted a nuclear power plant - it wanted nuclear technology, which it has now acquired.

Option 3 is starting to look like a frontrunner.
