Bruce's lengthy statement continued, "Prior to the United States' successful military operation, Iran was amassing a growing stockpile of highly enriched uranium for which there was no credible peaceful purpose, and it was the only state producing highly enriched uranium, up to 60%, that does not have nuclear weapons."

White House officials continue to swagger, but there may be less cause for optimism than they would have the public believe

Iran is assessing the damage and lashing out over the American and Israeli airstrikes that damaged its nuclear sites.

The new assessment contrasted with U.N. agency view that Iran could resume enriching uranium in a “matter of months.”

Iranian President Masoud Pezeshkian has approved a law to halt cooperation with the International Atomic Energy Agency (IAEA), a move which will likely obscure any attempt by Tehran to restart its damaged nuclear program.

The decision means that international inspectors will not be able to oversee sites. Experts have warned that Tehran could revive plans to build a bomb.

The Iranian government has suspended cooperation with the U.N.'s International Atomic Energy Agency until the security of Iran's nuclear facilities and activities is assured.
