Vice President of the United States J.D. Vance said on Saturday that the President donald trump While he and his team were busy in peace talks with Iran in Islamabad, Pakistan, he was called “a dozen times”.Speaking to reporters, Vance said, “We were constantly talking to the President. I don’t know how many times we spoke to him – half a dozen times, a dozen times in the last 21 hours.“Vance said, “We were in constant contact with the team as we negotiated in good faith. And we’re leaving with a very simple offer here, as a way to understand that this is our final and best offer.”Talks between America and Iran are currently at a standstill after no agreement was reached. According to Vance, the main controversy remained Iran’s nuclear program.The vice president called on Iran to shut down its program and stop uranium enrichment, calling it a “red line” for the Trump administration.“The simple fact is that we need to see a positive commitment that they will not seek nuclear weapons and that they will not seek equipment that would enable them to quickly acquire nuclear weapons,” Vance said.He said this is “the main goal of the President (Donald Trump)” and that is what he has tried to achieve through negotiations.Vance told reporters, “But the simple fact is that we need to see a positive commitment that they will not seek nuclear weapons, and they will not seek equipment that would enable them to quickly acquire nuclear weapons.”Meanwhile, Iran said the demands made by the US are “unreasonable” and blamed the US for the failure of the talks.“Before the talks, I stressed that we have the necessary goodwill and will, but because of the experiences of the last two wars, we have no confidence in the opposing side,” Iran’s parliament speaker Mohammad Bagher Ghalibaf wrote on Twitter.He said the Iranian delegation took constructive initiatives, “but in this round of talks the other side was unable to gain the confidence of the Iranian delegation.”He said, “America has understood our logic and principles and now the time has come for it to decide whether it can earn our trust or not.”Iran has long denied seeking nuclear weapons but has insisted on its right to a civilian nuclear program. Experts say its rich uranium reserves, though not weapons-grade, are only a small technological step away.Since the US and Israel launched the war on February 28, at least 3,000 people have been killed in Iran, 2,020 in Lebanon, 23 in Israel and more than a dozen in Gulf Arab states, and there has been permanent damage to infrastructure in half a dozen Middle Eastern countries. Iran’s hold on the Strait of Hormuz has largely cut off the Persian Gulf and its oil and gas exports from the global economy, driving up energy prices.Pakistani Foreign Minister Ishaq Dar said his country would try to facilitate a new dialogue between Iran and the US in the coming days.“It is important that the parties maintain their commitment to the ceasefire,” Dar said.The standoff – and Vance’s ‘take it or leave it’ proposal that Iran end its nuclear program – mirrors nuclear talks in Switzerland in February. Although President Donald Trump has said the subsequent war was aimed at forcing Iran’s leaders to abandon nuclear ambitions, each side’s positions appeared unchanged in talks after six weeks of fighting.
