Iran is becoming nuclear, which Israel regards as an existential threat it cannot accept.

Judge as of 2022-10-28. The claim has two parts: (a) Iran was advancing toward nuclear weapons capability (e.g. enrichment to high levels, shorter breakout time); and (b) Israel's official position treats a nuclear-armed Iran as an existential threat it will not accept. True: IAEA or credible reporting from 2022 shows Iran's nuclear program advancing (e.g. 60% enrichment, breakout time of weeks), and Israeli leaders' statements describe it as an existential or unacceptable threat. Mostly true: both parts hold, but 'becoming nuclear' overstates things where the evidence shows threshold capability rather than an active weapons decision. Mixed: one part holds clearly and the other only weakly. Mostly false: Iran's program was static or rolled back while Israel's stance holds. False: evidence contradicts both parts.

   “The fact that Iran’s diminishing breakout time, or the period it would take to produce enough weapons-grade material for a bomb, is less than 10 days”

   “Grossi said the IAEA estimated that Iran had produced 42 kilograms of uranium enriched to 60 percent uranium-235.”

   “stands just a few weeks away from accumulating fissile material that will be sufficient for a first bomb.”

   “According to official U.S. assessments, Iran halted its nuclear weapons program in late 2003 and has not resumed it.”

   “"At the same time, Israel will do anything we believe is needed to stop the Iranian nuclear program. Anything. From our point of view, the Iranian threat is not theoretical. The Iranians want to destroy Israel. They will not succeed. We will not let them."”

   “Lapid stressed that "Iran is not an Israeli problem. The world cannot afford a nuclear Iran. The world cannot afford for the Iranian Revolutionary Guard Corps to continue spreading terror around the globe.”

   “We will do whatever it takes: Iran will not get a nuclear weapon.”

8. E8 IAEA reports no progress in Iran as uranium stock enriched to 60 percent grows - The Korea Times The Korea Times (Reuters) · 5 September 2023

   “Adding to the issues likely to cause tension with the West, Iran's stock of uranium enriched to up to 60 percent grew by an estimated 7.5 kilogram to 121.6 kg, the report said, even though 6.4 kg of it was diluted with uranium enriched to a lower level.”

Reporting from 2022 shows Iran's program advancing: the IAEA estimated 42 kg of uranium enriched to 60% (E2), Iran was described as a few weeks from enough fissile material for a first bomb (E3), and its breakout time was put at under 10 days (E1). Israeli leaders said Iran wants to destroy Israel, that Israel would do "anything" to stop the program, and that "Iran will not get a nuclear weapon" (E5, E6, E7). Together these statements treat a nuclear-armed Iran as unacceptable. However, official U.S. assessments said Iran had halted its weapons program in 2003 and had not restarted it (E4). That points to threshold capability rather than an active weapons decision, so "becoming nuclear" overstates the situation somewhat.
