Iranian authorities have vowed to boycott the second round of peace negotiations between the United States and Iran, which are scheduled to take place in Pakistan this week. This is because the US detained an Iranian-flagged ship near the Strait of Hormuz over the weekend. US President Donald Trump has stated that it is extremely improbable that the two-week ceasefire between Tehran and Washington will be prolonged. The ceasefire is scheduled to expire on Wednesday.
Iran, on the other hand, claims that Trump is trying to convert the negotiating table into a table of surrender or to justify more belligerence by enforcing a blockade and breaking the truce."We do not accept negotiations under the shadow of threats, and in the past two weeks, we have prepared to reveal new cards on the battlefield," stated Mohammad Bagher Ghalibaf, the speaker of Iran's strong parliament and Iran's principal negotiator with the United States, in a post on X.
In addition, Ghalibaf warned that Tehran would have "new cards" if the conflict with the US and Israel resumed. "We do not accept negotiations under the shadow of threats, and in the last two weeks we have been preparing to show new cards on the battlefield," he wrote to X.

The Hormuz Issue
The impasse in and around the Hormuz Strait, a vital waterway that has become a major issue in peace negotiations, has continued to intensify despite both the US and Iran expressing hope of negotiating an end to the war.
What the United States Said
The US delegation will attend peace negotiations in Pakistan this week, according to the Trump administration. The US president originally stated that negotiations would take place in Islamabad on Tuesday, but that date may be rescheduled. In addition to Trump's son-in-law Jared Kushner and his Middle East special envoy Steve Witkoff, Washington is once again sending a delegation headed by Vice President JD Vance to the negotiations.But amid the uncertainty surrounding negotiations, Trump has delivered a dire warning, saying that "then lots of bombs start going off" if the precarious two-week ceasefire with Iran expires without a resolution.
Trump was asked in an interview with PBS News what would happen if the ceasefire ended. "Then lots of bombs start going off," he replied.They should be there, after all. They claim we didn't consent to be there, but we did. No, it was put up. And we'll check to see whether it exists. It's okay if they're not present," he continued.

The Arguments
Speaking to The Washington Post under condition of anonymity, an Iranian official stated that the two biggest threats to negotiations are the tone of Trump's public remarks and the continuous US blockade.
They asserted that although the two parties had virtually reached an agreement on the general parameters of a deal, Trump's public "maximalism" ran the risk of undermining the diplomatic advancement.
According to reports, mediators in Pakistan have also warned the Trump administration not to use strong public rhetoric. According to a Pakistani official who spoke to The Post, they also pushed the US president to accept the narrative that the negotiations in Islamabad were a "win-win" for Iran and the US.
