What are the Iranians up to?

I read that:

"the International Atomic Energy Agency said Iran continued to expand its uranium enrichment program despite three sets of U.N. Security Council sanctions meant to pressure Tehran into freezing such activities.... Drawing heavily on language of previous reports, the Iran document said Tehran has not "cooperated with the agency ... which gives rise to concerns and which need to be clarified to exclude the possibility of military dimensions to Iran's nuclear program." The report noted that Tehran continued to rebuff agency efforts to investigate suspicions the Islamic Republic had at least planned to make nuclear weapons. Without cooperation by the Islamic Republic, the IAEA "will not be in a position to provide credible assurance about the absence of undeclared nuclear material and activities in Iran," the report said. The IAEA's Iran report reflected continued expansion both in the terms of the equipment in use or being set up and the amount of enriched uranium being turned out by those machines — centrifuges that spin uranium gas into enriched material. Nearly 5,000 centrifuges were processing uranium gas as of May 31, said the report, while more than 2,000 others were ready for operation. More than nearly 3,000 pounds — 1,300 kilograms — of low enriched uranium had been produced as of that date, said the more than four-page report. That compares to just over 2,220 pounds (1,000 kilograms) mentioned in the last IAEA report in February an amount that experts and U.S. officials subsequently said was enough to process into enough weapons grade uranium for a nuclear warhead."

It is clear to everyone that the Iranian government are trying to produce nuclear weapons. It is clear to many people that the Iranian government want to use such warheads to threaten and maybe destroy Israel. And the reaction of the world? Nothing or next to nothing. Iran is a threat to world peace but it is Israel that is told to restrain itself as it faces possible annihilation.
