Iran’s Supreme Leader Shuts Down Nuclear Talks

[01:30–06:34]

Key Discussion Points

• Hardening Iranian position:

  • Iran’s Supreme Leader (or his close circle) has officially ordered that Iran’s weapons-grade uranium will not be shipped abroad.
  • Two senior Iranian officials told Reuters this is non-negotiable, making it even tougher to reach any peace deal.

• The U.S. and Israeli red line:

  • President Trump has assured Israel that any final agreement must include the complete removal of Iran’s highly enriched uranium, enriched up to 60%.
  • 60% enrichment is significant:

    “Once uranium reaches 60% enrichment, the hardest part of the process is already done. The remaining jump to weapons grade can happen far more quickly than going from 0 to 60.”
    — Mike Baker [03:30]

• Israeli demands:

  • Israeli PM Netanyahu will not end the conflict unless:
    • Uranium is removed from Iran
    • Iranian proxy support stops
    • Iran’s missile program is dismantled

• Iranian distrust:

  • Tehran considers shipping out uranium a security threat, fearing increased vulnerability to future Israeli or U.S. strikes.
  • Iran suspects the current ceasefire is merely a U.S. pause to regroup for further attacks.

• Ongoing mediation and brinkmanship:

  • Pakistan is attempting mediation but progress is stymied
  • Tension remains high over U.S. blockade of Iranian ports and control over Strait of Hormuz

• Iranian skepticism and negotiating tactics:

  • Iran previously floated the idea of exporting half its stockpile, but now draws a hard line.
  • Direct supervision by the IAEA and “diluting” the stockpile could be up for negotiation—if the U.S. and Israel guarantee no further attacks.

Memorable Quotes & Moments

• Iran’s top negotiator warns:

  “Obvious and hidden moves by the enemy show the Americans are preparing fresh attacks.”
  — Mohammed Bakar Galiboff, Iran’s top negotiator [05:02]

• Baker's analysis:

  “This is no longer just a dispute over nuclear material. For Iran, the uranium stockpile is now tied directly to their survival. For the U.S. and Israel, allowing that material to remain inside Iran may be politically and militarily unacceptable. And that leaves the entire ceasefire, such as it is, at the mercy of one question: who blinks first?”
  — Mike Baker [06:30]

Taiwan Tensions Explode After Trump Suggests Direct Talks

[09:54–14:44]

Key Discussion Points

• Trump disrupts decades of protocol:

  • Less than a week after returning from Beijing, President Trump signals openness to direct talks with Taiwan’s President Lai Ching Te regarding a $14 billion U.S. arms package.
  • This would break a diplomatic “red line” since 1979, when the U.S. formally severed direct ties with Taipei to normalize with Beijing.

• The gravity of 'the Taiwan issue':

  • China views any official U.S.–Taiwan contact as a core, existential threat.
  • Xi Jinping reiterated this in Beijing, warning mishandling Taiwan could push U.S.–China relations to confrontation level.

• Historic parallel:

  • Baker recalls how Trump first shook this precedent in 2016, as president-elect, when he took a call from then Taiwanese President—sparking immediate outrage from Beijing.

• Current developments:

  • Taiwan’s Foreign Ministry welcomes the possibility of a call, but no communication has taken place yet.
  • The real shift is the context: the $14 billion arms package would provide missiles, anti-drone, and advanced air defense systems aimed at deterring Chinese military action.

• Washington and Beijing’s maneuvering:

  • While U.S. law requires aiding Taiwan’s defense, China sees arms sales and official contact as challenges to its sovereignty.
  • China is reportedly delaying talks with the Pentagon, waiting to see what Trump does on the arms deal.
  • Trump has openly framed the deal as a “negotiating chip” with Beijing, indicating a willingness to use Taiwan as leverage, not simply as a partner in deterrence.

Memorable Quotes & Moments

• Trump hints at new precedent:

  “I’ll speak to him [Lai],”
  — President Trump, per reporters’ queries on Air Force One [Referenced ~10:30]

  “We’ll work at the Taiwan problem.”
  — President Trump [Referenced ~10:40]

• Host’s warning on the stakes:

  “That phrasing is significant, particularly from China’s perspective, probably more than you even realize at first glance, because Taiwan is viewed by the Chinese leadership as existential and tied to President Xi Jinping’s long-term ambitions.”
  — Mike Baker [10:45]

• Analysis of Trump’s posture:

  "The call itself is almost becoming secondary to what's happening around it... the massive new weapons package now hanging over the relationship.... Trump may not be viewing Taiwan solely through the traditional lens of deterrence. Instead, Trump may see Taipei as leverage in the competition between Washington and Beijing."
  — Mike Baker [12:50]

Episode Takeaways

• Nuclear talks with Iran have hit a dead end over control of near weapons-grade uranium. The ceasefire remains fragile, and escalation is possible as all sides draw red lines.
• U.S.–China relations are under fresh strain as President Trump’s willingness to speak with Taiwan’s president and discuss major weapon sales threatens to upend decades-old diplomatic agreements.
• Both flashpoints are tied to deeper questions of trust, credibility, and survival—making the coming weeks extremely volatile for U.S. foreign policy.

The 21st of May. Welcome to the PDB Afternoon Bulletin. I'm Mike Baker, your eyes and ears on the world stage. All right, let's get briefed. First up, Iran's supreme leader or whomever speaks for him just slammed the door on one of Trump's main demands, ordering that the country's near weapons grade uranium stockpile will stay put and will not leave Iranian soil later in the show. It's just one week after President Trump's meeting with Chinese President Xi Jinping and the goodwill supposedly generated at the summit may be out the window. Trump says he's ready to speak with Taiwan's President Lai Ching Te on arms deals. That's a direct challenge to Beijing that blows up decades of diplomatic precedent. But first, today's afternoon spotlight. Iran's supreme leader has just drawn a very hard line on one of the biggest sticking points in the US Brokered peace talks. The country's stockpile of near weapons grade uranium, reportedly, according to Mushtab Ahawani, is not to leave Iranian soil. Now that's according to Two senior Iranian sources who spoke to Reuters on condition of anonymity. And it's likely to make a peace deal between the US and Iran even more difficult to reach. Ayatollah Moshtaba Khamenei's directive, if it did in fact come from him, comes as President Trump has reportedly assured Israel that any final deal must include the complete removal of that highly enriched uranium. That's material enriched to 60%, which is far beyond anything typically needed for civilian purposes, and just shy of the 90% enrichment that's required for a weapon. Put simply, and this is very simplistic, Once uranium reaches 60% enrichment, the hardest part of the process is already done. The remaining jump to weapons grade can happen far more quickly than going from 0 to 60. Israeli officials tell Reuters that Netanyahu has been crystal clear the war does not end until the uranium is out. Iran's support for proxy militias is severed and its ballistic missile program is dismantled. Tehran, for its part, now views shipping the stockpile abroad as an unacceptable security risk that would leave the country more vulnerable to future US or Israeli strikes. The shaky ceasefire, or whatever we're calling the arrangement, has been in place since 7th April. Since then, Pakistan has been trying to mediate. But a full US blockade of Iranian ports and Tehran's continued control over the Strait of Hormuz have kept tensions high inside the Iranian establishment. There's deep suspicion that the pause in fighting is simply a tactical pause by Washington and buying time before another round of airstrikes. Iran's top negotiator, Mohammed Bakar Galiboff, said just yesterday that, quote, obvious and hidden moves by the enemy show the Americans are preparing fresh attacks, end quote. President Trump stated Wednesday that the U.S. is ready to hit the regime again if a deal isn't reached, though he indicated Washington could wait a few more days for the right answers, which of course is a very familiar pattern by now. Threaten more strikes. Allude to positive developments in the negotiating process. Mentioned that strikes will be delayed, but could happen. Express frustration with the negotiations. Wash, rinse and repeat. Before the war, Iran had signaled it might ship out roughly half of its 60% stockpile. That position has now hardened, although to be fair, the regime does not have a habit or a track record of following through on supposed plans or promises. The IAEA's latest estimate that came before the June 2025 strikes on Iranian nuclear sites put the stockpile at 440.9 kg. Its roughly 200 kg are believed to remain mainly stored in tunnel complexes at isfahan in Natanz, Iran, insists some highly enriched uranium is needed for medical isotopes. And its Tehran research reactor sources say Tehran's priority remains the same ironclad guarantees that the US And Israel will not attack again before any serious nuclear negotiations begin. Once those assurances are in place, Iranian officials say that they're open to detailed talks. They even floated what they're calling, quote, feasible formulas, such as diluting the stockpile under direct IAEA supervision. Bottom line, this is no longer just a dispute over nuclear material. For Iran, the uranium stockpile is now tied directly to their survival. For the US And Israel, allowing that material to remain inside Iran may be politically and militarily unacceptable. And that leaves the entire ceasefire, such as it is, at the mercy of one question, who blinks first? All right, coming up next, President Trump says he'll speak directly with Taiwan's President Lai Ching Te about arms sales shattering decades of U.S. diplomatic protocol. I'll be right back.

[Mike Baker]

Welcome back to the PDB Afternoon bulletin. Less than a week after leaving Beijing, President Trump is raising the possibility of speaking directly with Taiwan's president, skirting a diplomatic red line that has long sat at the center of U. S. China tensions. Now, to understand why this gets Beijing's attention, you have to recognize just how sensitive this issue has been for decades. Since formally severing diplomatic ties with Taipei back in 1979, the White House has very carefully avoided direct presidential contact with Taiwan's leadership. That balancing act has served as one of the foundational guardrails holding the modern U. S. China relationship together, and President Trump now appears willing to possibly disturb that delicate balance. This is the second time in a week that Trump publicly raised the possibility of Speaking directly with Taiwanese President Lai Ching Te. The first was on board Air Force One returning from Beijing. And then later, when reporters asked whether he planned to call Lai before deciding on the massive 14 billion dollar weapons package for Taiwan, Trump told reporters, quote, I'll speak to him, referring to Lai, before later saying something else that almost certainly caught Beijing's attention. He said, quote, we'll work that the Taiwan problem, end quote. Now, that phrasing is significant, particularly from China's perspective, probably more than you even realize at first glance, because Taiwan is viewed by the Chinese leadership as existential and tied to Chinese President Xi Jinping's long term ambitions. And Xi made that very clear during last week's summit in Beijing. According to China's official readout and what we've been tracking here on the pdb, Xi warned Trump that Taiwan remains, quote, the most critical issue between the two countries and cautioned that mishandling it could push Washington and Beijing toward confrontation. That sensitivity helps explain why Trump already rattled Beijing once before on this exact issue. Back in 2016, shortly after winning the presidential election, Trump spoke by phone with the then Taiwanese president, becoming the first president or president elect to speak directly with the Taiwanese leader since diplomatic ties were cut at the time. The call triggered immediate backlash from Beijing, with China's foreign minister dismissing it as, quote, a petty action by the Taiwan side. Now, nearly a decade later, Trump appears willing to push even further. Taiwan's Foreign Ministry responded to the possibility of direct talks with Trump today, saying Lai would be happy to speak with the president, But I want to point out that so far it's all talk and nothing official. Lai's office says it has not received any communication from Washington. But at this point, the call itself is almost becoming secondary to what's happening around it. And that would be, of course, the massive new weapons package now hanging over the relationship. The proposed $14 billion sale includes missiles, anti drone systems and advanced air defense capabilities specifically designed to strengthen Taiwan against Chinese military coercion or invasion. Under American law, the US Is required to provide Taiwan with the means to defend itself and and lawmakers from both parties continue pushing the administration to move forward with this sale. But Beijing views the arms package and any expansion of official U. S. Taiwan contact as direct challenges to China's sovereignty claims over the island. According to the Financial Times, Beijing is delaying a proposed visit by Pentagon Undersecretary of Defense for Policy Elbridge Colby while CCP officials wait to see whether Trump ultimately approves the weapons package. At the same time, Trump says he still has not made a final decision on whether to move forward with the sale, and that uncertainty may be intentional. After departing China, Trump described the arms package as a possible, quote, negotiating chip. That suggests Trump may not be viewing Taiwan solely through the traditional lens of deterrence. Instead, Trump may see Taipei as leverage in the competition between Washington and Beijing. And that, my friends, is the PDB Afternoon bulletin for Thursday 21st May.
