US President Donald Trump announced that Vice President JD Vance will not lead the American delegation for the second round of negotiations with Iran in Islamabad, Pakistan, due to security concerns. This decision comes after the first round of talks, held the previous weekend, did not yield any results. Vance, who has been perceived as less enthusiastic about US military interventions, faced criticism for his comments comparing Iran's uranium-enrichment demands to personal freedoms. Instead of Vance, Trump's special envoys, Steve Witkoff and Jared Kushner, will represent the US in the upcoming discussions. Iran's chief negotiator, Mohammed Bagher Ghalibaf, stated that there will be no retreat in diplomatic efforts, although significant gaps remain between the two sides. In anticipation of the talks, Pakistani authorities have increased security measures in Islamabad.
