“News that the U.S. and Iran had reached an interim deal may have brought some initial relief to markets, but fresh uncertainty emerged on Friday after planned follow-up talks in Switzerland were called off, underscoring the challenges of turning the agreement into a lasting peace settlement,” CNBC reports.

“Switzerland’s foreign ministry said U.S.-Iran talks scheduled to take place at Bürgenstock on Friday would not proceed as planned.”

NewsNation: What happens now that the US-Iran peace deal has been called off?

“As another round of negotiations to review a North American free-trade deal wraps up in Washington this week, lawmakers are growing more vocal in defense of the deal, and anxious about its future,” the New York Times reports.

“President Trump has said he’s not sure whether he will renew the six-year-old United States-Mexico-Canada Agreement. While many view the president’s threats as a negotiating tactic, they are still causing concern among members of Congress whose districts depend on the agreement.”

New York Times: “More than 3,000 Iranians were reported to have been killed in the conflict. Israel says 26 Israelis have been killed. Thousands of people in both countries have been injured.”

“The U.S. military says 13 of its members have been killed.”

“Israel renewed attacks on Lebanon on March 18 as part of the wider war, and about 3,700 people have been killed there, according to Lebanon’s health ministry.”

NOTUS: “The U.S. and Iran are expected to begin talks this weekend in Switzerland toward a permanent end to the war. They have 59 days to agree on contentious issues, including Iran’s nuclear program, economic sanctions and a new regional arrangement governing the Strait of Hormuz.”

“It’s a particularly delicate period, but Trump remains deeply volatile. The negotiations will test the “madman theory” of foreign policy the president leans on: assuming adversaries will cave because they don’t know how far he will go. They will also test whether U.S. officials can reach mutually agreeable terms when their boss might shift the goalposts at any time — an especially significant task given how massive the global cost of resuming conflict with Iran has become.”

Vice President JD Vance on Thursday defended the preliminary deal to stop the war with Iran as a “win for the American people.” But he relied in part on a string of aspirational, vague and misleading claims about the agreement, the New York Times reports.

Vice President JD Vance is no longer traveling to Switzerland tonight as previously planned for the signing of a memorandum of understanding with Iran, a White House spokesperson said, citing unresolved logistics surrounding the next phase of negotiations, CNN reports.
