Talks in Pakistan between American and Iranian representatives ended without an agreement after 21 hours of negotiations, leaving a two-week ceasefire in doubt.

Vice President JD Vance, who led the U.S. delegation in Islamabad, said talks came to a close after Iranian counterparts refused to agree to terms that stipulated Iran would cease its nuclear development efforts.

After the talks, Iranian ambassador to Pakistan, issued a statement saying the talks were not a one-off event, but the beginning of a “process.”

Not long after news broke of the stalemate, President Donald Trump announced the U.S. Navy would stop any vessel that attempts to enter or leave the Strait of Hormuz.

WTOP National Security correspondent J.J. Green joined Sandy Kozel to discuss the latest development, and what it could mean for future negotiations.

The interview was lightly edited for clarity.

Timeline of decades of conflict between Israel and Hezbollah

BEIRUT (AP) — The ongoing war between Israel and the Lebanese militant group Hezbollah is far from the first conflict between them. The two have an enmity that goes back more than four decades, with outbursts of fighting or outright war punctuated by periods of tense calm. Here is a timeline of some significant events in the hostilities between the two: 1982: Israel invades Lebanon in an offensive against the Palestine Liberation Organization and allied groups. Hezbollah is formed, with Iranian backing and based on the Iran's Islamic Revolution model, to fight Israel’s ensuing occupation of southern Lebanon. It launches a guerrilla war against Israel. 1992: Hezbollah leader Abbas Mousawi is killed by an Israeli helicopter attack. His successor is Hassan Nasrallah, who will lead the group for the next three decades.
