The three-year-old agreement called for lifting sanctions on Iran that had hobbled its economy in exchange for Iran restraining its nuclear program, which Iran has claimed was for peaceful purposes. Israeli Prime Minister Benjamin Netanyahu has long criticized the deal and in Trump found an ally with similar views.
Among Trump’s chief objections are a lack of provisions addressing Iran’s ballistic missile activity and the fact that Iran’s responsibilities, such as limiting its uranium enrichment, expire after a set number of years.
In his speech, Trump said the current deal would leave Tehran “on the cusp” of a “nuclear breakout.”
The text of the document, formally known as the Joint Comprehensive Plan of Action, states in multiple places that Iran would treat the reinstatement of sanctions.
