Conference at UN to review nuclear nonproliferation treaty fails to reach agreement

UNITED NATIONS (AP) — A four-week United Nations conference reviewing the treaty to prevent the spread of nuclear weapons ended Friday without agreement as the United States and Iran sparred over Iran's nuclear program.

Vietnam's U.N. Ambassador Do Hung Viet, who chaired the conference, announced that there was no consensus among the 191 parties to the Nuclear Nonproliferation Treaty on even a watered-down final document.

He told a news conference later that “no one blocked consensus.” But he said “a very important reason” for the failure to reach an outcome was a provision in the final draft that said Iran “can never seek, develop or acquire any nuclear weapons.”

It was the third failure in a row at a conference reviewing the NPT, considered the cornerstone of global nonproliferation and disarmament. At the last treaty review in August 2022, Russia blocked agreement on a final document over its February 2022 invasion of Ukraine and references to Moscow’s occupation of the Zaporizhzhia nuclear power plant, Europe’s largest.

Tensions over Tehran’s nuclear program escalated ahead of the Iran war, which began with U.S. and Israeli airstrikes on Feb. 28. President Donald Trump has said the war was aimed at preventing Iran from developing a nuclear weapon. Iran has enriched uranium to near weapons-grade levels but insists its program is only for civilian purposes.

The U.S. and Iran have clashed since the opening of the review conference on April 27. The U.S. has accused Iran of showing “contempt” for its commitments under the treaty, while Iran has said U.S. and Israeli attacks on its nuclear facilities violated international law.

Iran is a party to the NPT, which requires countries to open all nuclear sites to inspection by the U.N. nuclear watchdog agency. But Iran has not given inspectors from the International Atomic Energy Agency access to nuclear sites that were bombed by the U.S. last June.

Daryl Kimball, executive director of the Washington-based Arms Control Association, said the United States insisted that Iran be named in the outcome document for its refusal to comply with its NPT obligations, including inspections, and it was. Iran objected to being singled out and insisted that the U.S. and Israel be condemned for attacking its nuclear sites, which violates the NPT, but that was not included, he said.

In speeches at the end of the conference, the United States called Iran a “prolific treaty violator” and said it had spent the conference “shirking accountability for its grotesque violations.” Iran accused the U.S. and its allies of conducting a “relentless campaign” to legitimize their “unlawful attacks” on the country and its nuclear facilities.

Kimball said the conference “showed that rhetorical support for the NPT is strong, but the foundations of the NPT are cracking due to inaction, inattention, and intransigence on the part of the major powers.”

“Much more enlightened, engaged, and pragmatic leadership and diplomacy will be needed to guard against the growing risks of an unconstrained nuclear buildup, threats to resume nuclear testing, and the risk of a nuclear-armed Iran," Kimball said.

Britain’s Rebecca Johnson, founding executive director of the Acronym Institute for Disarmament Diplomacy, had harsh criticism for both the U.S. and Russia, the two largest nuclear powers, which she said "double down on nuclear threats, blame others and try to undermine or ignore the NPT’s nuclear disarmament commitments and related agreements,” including on nuclear testing.

TORONTO (AP) — The Pittsburgh Pirates recalled prospect Esmerlyn Valdez from Triple-A Indianapolis after a recent hot streak and had him in the lineup in right field Friday night for their game at Toronto.

Valdez was 0 for 3 with a groundout, two strikeouts and a walk in his major league debut, a 6-2 Pirates loss.

Valdez, 22, hit five home runs in the last five Triple-A games and was batting .355 with seven extra-base hits, 10 RBIs, a .903 slugging percentage and 1.315 OPS in his last eight.

Valdez hit .253 with 10 homers, 10 doubles and 29 RBIs in 46 games with Indianapolis this season. He also has 33 walks.

The right-handed hitter is the organization's No. 9 prospect, according to MLB Pipeline. He led Pittsburgh’s minor league system with 26 home runs last season and represented the club at the All-Star Futures Game.

Valdez was signed by Pittsburgh as a nondrafted free agent on Jan. 15, 2021.

Pittsburgh optioned outfielder Billy Cook to Indianapolis following Thursday’s game at St. Louis.
