Iran has issued a stark warning to the United States, stating it is prepared to retaliate 'to the last drop of blood' as tensions escalate over a military blockade. The Iranian military has indicated that swift action could follow if US forces advance further, reflecting a significant shift from previous restraint. The Strait of Hormuz has been closed from the Arabian Sea side, heightening pressure in the region. This warning comes amid a standoff that has lasted 61 days, with the US and Israel having previously conducted coordinated strikes that killed Iran's Supreme Leader Ali Khamenei. The US has rejected Iran's proposal to ease the blockade, with President Donald Trump asserting that the blockade is more effective than military action. The ongoing conflict centers on Iran's insistence on its right to enrich uranium and the US's demands for the dismantling of Iran's nuclear program. As both sides remain firm on their positions, the risk of further escalation looms.
