Talks between the United States and Iran collapsed after more than 20 hours of negotiations in Islamabad, sparking renewed fears of conflict across the Middle East. US Vice President JD Vance acknowledged that the differences between the two sides were too deep to resolve for now. Soon after, President Donald Trump ordered an immediate naval blockade in the Strait of Hormuz, warning that any ship paying tariffs to Tehran would be seized and threatening to cut Iran off from future oil revenues.

The breakdown of talks has heightened uncertainty in an already volatile region. Citizens from Doha, Tel Aviv, Tehran, Abu Dhabi, and Saudi Arabia expressed anxiety about the prospect of renewed warfare. In Israel, a recent survey showed only 10 percent viewed the conflict with Iran as a success, while 32 percent saw it as a failure. In Iran, brief hopes for peace quickly faded, with many fearing an inevitable return to war.

In Lebanon, disputes over whether the country was included in the ceasefire agreement have led to intensified Israeli attacks. Observers warned that the collapse of negotiations could have global repercussions if peace efforts fail to regain momentum.
