A mysterious explosion and fire at Iran’s main nuclear facility may have stopped Tehran from building advanced centrifuges, but it likely has not slowed the Islamic Republic in growing its ever-increasing stockpile of low-enriched uranium. Limiting that stockpile represented one of the main tenets of the nuclear deal that world powers reached with Iran five years ago this week — an accord which now lies in tatters after President Donald Trump unilaterally withdrew America from it two years ago. The larger that stockpile grows, the shorter the so-called “breakout time” becomes — time that Iran would need to build a nuclear weapon if it chooses to do so.
