Tehran maintains that the ball is now in the U.S. court, asserting that Washington must return to the table with a &quot;more realistic approach&quot; that includes <strong>sanctions relief<\/strong> and the unfreezing of assets.<\/p>\n<p>The international community, led by <strong>Australia\u2019s Foreign Affairs Minister Penny Wong<\/strong>, has expressed deep disappointment over the stalemate. Australia has called for the immediate continuation of the current ceasefire, warning that any escalation would impose a &quot;greater human cost&quot; and further destabilize the global economy.<\/p>\n<p>Market analysts are closely monitoring major energy firms like ExxonMobil (<a href=\"\/stock\/XOM\">XOM<\/a>) and Chevron (<a href=\"\/stock\/CVX\">CVX<\/a>) as the threat of a naval blockade looms. <em>A full-scale blockade would likely solidify the current spike in global fuel costs<\/em>, as the Strait of Hormuz serves as the transit point for approximately <strong>20% of the world&#39;s oil supply<\/strong>.<\/p>\n<p>While some technical teams remain in Islamabad, the departure of the primary U.S. delegation suggests a shift back toward military and economic pressure. <em>The &quot;Trump card&quot; of a blockade signals a transition from diplomatic engagement to a strategy of total maritime containment<\/em>, leaving global shipping lanes in a state of high-alert.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways High-stakes peace talks in Islamabad collapsed after 21 hours of intensive negotiations failed to produce a deal between
