Iran has renewed its threats against U.S. bases in the Middle East in a letter to the UN Secretary-General, stating that any military aggression by the United States would be met with a decisive and proportional response, making all American bases, infrastructure, and assets in the region legitimate targets. This comes as U.S. President Donald Trump has given himself "ten" to "fifteen days" to decide whether to pursue a deal with Iran or resort to force, reiterating that "bad things" will happen without a "relevant" agreement. Despite ongoing talks, relations remain tense, with Iran's supreme leader also threatening to sink a U.S. aircraft carrier in the Gulf, while Iran's Revolutionary Guard conducts military exercises in the Strait of Hormuz.
