WASHINGTON — Nikki Haley, President Donald Trump’s envoy to the United Nations, will travel to Vienna next week to discuss the US government’s concerns about the Iran nuclear deal with the International Atomic Energy Agency (IAEA). The high-profile visit comes as the former South Carolina governor has staked out a hard line on Iran and sharply pro-Israel positions, perhaps with an eye to her own future political ambitions.

Haley will hold meetings with IAEA leaders and experts in Vienna on Wednesday, the US mission to the UN confirmed to Al-Monitor. “She will meet with IAEA leadership, Iran safeguards experts and others,” a spokesperson said.

The IAEA has consistently certified Iran’s compliance with the Iran nuclear deal, which was reached in 2015 after years of negotiations and went into force in 2016. In addition to requiring Iran to remove several thousand centrifuges from its Natanz uranium enrichment facility, pour concrete into the core of its plutonium reactor and turn its underground Fordow enrichment facility into a research site, the Joint Comprehensive Plan of Action (JCPOA) also set up what negotiators have called the most extensive nuclear inspections and monitoring regime in history.

But Haley, ahead of the trip, signaled she was skeptical of Iran’s compliance with the deal, and vowed the Trump administration would not be held hostage to it.
