In a dramatic move, US President Donald Trump has ordered the United States Navy to impose a blockade on the Strait of Hormuz, a critical waterway for global oil transport, following failed negotiations with Iran regarding its nuclear program. Trump stated that the blockade is effective immediately, aiming to prevent any ships from entering or leaving the strait. The announcement came after US Vice President JD Vance's talks in Islamabad with Iranian officials, including parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, ended without an agreement. Trump criticized Iran for its failure to adhere to promises regarding the strait and threatened severe consequences for any attacks on US or peaceful vessels. The US military had previously initiated a mine clearance operation in the strait, which Iran contested, claiming it had prevented US warships from crossing. Tensions remain high as Iran's military has warned of a strong response to any American naval presence in the area.
