Iran continues to enrich uranium despite Biden's efforts and UN sanctions for its nuclear weapons program.

This week, the Islamic Republic of Iran responded to the Biden administration's backing of a moderate United Nations watchdog agency's criticism of Tehran's nuclear weapons program.

The IAEA confirmed on Monday that Iran has started using advanced IR-4 and IR-6 centrifuges at its Natanz enrichment facility to enrich uranium more quickly, with cascades of centrifuges spinning uranium gas together.

Up to 2% purity, Iran has been enriching uranium in those cascades. Iran is now on the brink of achieving weapons-grade levels of 90% purity, just a short technical step away.

Avigdor Lieberman, a former Defense Minister of Israel and a member of the Knesset, stated on Israel's Army Radio that Iran is planning a Holocaust for the Jewish people in the next two years.

In a statement, Matthew Miller, a spokesman for the State Department, stated that Iran's move to expand its nuclear program has no credible peaceful purpose.

"These planned actions further undermine Iran's claims to the contrary. If Iran implements these plans, we will respond accordingly." Miller declined to specify what actions the U.S. government will take against the rogue regime in Tehran. The State Department has designated Iran's regime as the world's worst international state-sponsor of terrorism.

Behnam Ben Taleblu, a senior fellow at the Foundation for Defense Democracies, strongly disagreed with the U.S. State Department. He stated on Planet Chronicle Digital that "Although Washington has pledged to 'respond accordingly,' it has been the delayed response, missteps, and absorption of Tehran's previous nuclear moves that have led us to this point."

To reset the impression of the Islamic Republic's decision-makers about U.S. and Western resolve, Washington must aggressively enforce oil and petrochemical sanctions and militarily threaten what Tehran holds dear in the region.

This week, a State Department spokesperson informed Planet Chronicle Digital that the US remains concerned about Iran's nuclear program, as they have stated at the IAEA for years and reiterated today. Iran's history and ongoing failure to prove the peaceful nature of its nuclear program to the IAEA and the world highlight these concerns.

The Iranian regime continues to accumulate a growing stockpile of highly enriched uranium, which has no credible civilian purpose. We anticipate collaborating with other Board members on a sustainable and effective solution that requires Iran's full cooperation with the IAEA, particularly as we approach October 2025, a critical juncture for the international community's efforts to ensure that Iran's program remains peaceful.

The State Department spokesperson stated that the U.S. is working with E3 and the international community to increase pressure on Iran's regime, including a crackdown on Tehran's sale of oil to China. The goal is to counter Iran's destabilizing behavior and prevent them from obtaining a nuclear weapon, which President Biden has made clear he will not allow. Any suggestion that the U.S. is backing off is false.

The Iranian regime is continuing its hourglass strategy by expanding its atomic program while circumscribing international monitoring reports of more advanced centrifuges being installed and operated. This cannot be ignored by the administration, as these machines offer greater means to enrich more uranium in less time.

Iran plans to increase its uranium enrichment capabilities by installing 18 IR-2m centrifuges and eight IR-6 centrifuges at its nuclear sites. These centrifuges are faster than Iran's baseline IR-1 centrifuges, which remain the mainstay of its atomic program.

Ali Shamkhani, a former top security official within Iran's theocracy who still advises Supreme Leader Ayatollah Ali Khamenei, stated on X that Tehran remains committed to nuclear safeguards, but will not yield to pressure.

If they could, some Western countries, including the U.S., would dismantle Iran's nuclear industry, according to Shamkhani.

Following the collapse of Iran's 2015 nuclear deal with world powers, the country has pursued nuclear enrichment just below weapons-grade levels. The Trump administration withdrew from the atomic deal in 2018, arguing that the accord permitted Tehran to build a nuclear weapon. Planet Chronicle Digital revealed last year that Iran's regime continued to work on the construction of an atomic bomb.
