Donald Trump has flatly rejected Iran’s latest nuclear counter-proposal, calling it “totally unacceptable” and “a piece of garbage.”

The core issue: Iran’s proposal reportedly does not commit to dismantling its enrichment facilities or to a binding end of its nuclear weapons program.

What Iran actually proposed

According to The Wall Street Journal, Iran’s counter-offer included several conditions that collectively amounted to a non-starter for Washington.

Tehran offered to dilute some of its enriched uranium but also insisted on retaining the right to reclaim those materials if the agreement collapsed. Iran also demanded war reparations and sought recognition of its control over the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world’s oil supply passes daily.
