Well, the other thread with a predicted invasion date was a bit extreme. Here is an article with fairly detailed information about the state of affairs with respect to Iran's atomic program.
The most useful parts are highlighted below.
Criticism mounts over Iran
Asked if the council might impose sanctions, White House spokesman Scott McClellan said: "That's a possibility as well, that's one option that's available."
But Russia and China, veto-carriers at the Security Council, have hitherto opposed sanctions.
Several council members insisted it would stick to its plan, announced last month, not to consider further action until International Atomic Energy Agency chief Mohamed ElBaradei made a report at the end of April.
President Bush this week dismissed media reports of U.S. plans for strikes on Iran as "wild speculation."
Russian Foreign Minister Sergei Lavrov said the use of force was no answer to the standoff over Iran's nuclear program.
"If such plans exist they will not be able to solve this problem. On the contrary they could create a dangerous explosive blaze in the Middle East, where there are already enough blazes," he said.
China's U.N. Ambassador Wang Guangya said the Iranians' move was "not in line with what is required of them by the international community," but that talk of sanctions or military steps "will not be helpful under the current circumstances."
Diplomats said the five permanent members of the Security Council -- the United States, Britain, France, Russia and China -- plus Germany would meet in Moscow next week alongside a Group of Eight meeting to discuss Iran.
U.N. Secretary General Kofi Annan urged all parties to return to talks and "cool down the rhetoric."
Three European states behind a deal to suspend enrichment which broke down last year weighed in with criticism of Iran.
British Foreign Minister Jack Straw said the announcement was "deeply unhelpful" and undermined confidence. His German counterpart, Frank-Walter Steinmeier, said Iran was "going in precisely the wrong direction" for a return to negotiations.
French Foreign Minister Philippe Douste-Blazy said it was a worrying step and Iran should stop its "dangerous activities."
Deputy White House chief of staff Karl Rove said reaching a diplomatic solution with Iran "is going to be tough because they are led by ideologues who have a weird sense of history," and that Ahmadinejad was "not a rational human being to deal with."
The State Department said it was unable to confirm that Iran had enriched uranium and some experts said even if Tehran's assertions were accurate, it would still be years before the Islamic Republic was able to produce a nuclear weapon.
The level of enrichment needed for nuclear bombs is many times higher than the 3.5 percent Iran says it has reached.
It would take about two decades for Iran's current cascade of 164 centrifuges to yield enough highly enriched uranium for one bomb. But Tehran says it wants to install 3,000 centrifuges, which could produce enough material for a warhead in one year.
