"Gantz: Iran’s enriched high-grade uranium stock boosted fivefold to 50kg"

 Apr 6, 2022.

Reported in entirety as posted by DEBKA:

"Defense minister Benny Gantz, in a briefing to 80 foreign ambassadors on the security situation on Wednesday, disclosed that in the past year Iran had expanded it's 60pc [60 %] enriched uranium stock from 10kg to 50kg. 'There was no vacuum' in its nuclear program, he said. He added that if the Vienna negotiations fail to produce a deal to curb it, Plan B will become essential."

50 kg. = 110 pounds. Enriched uranimum U-235 presumably we are talking about and nothing else.

The gun-type uranium bomb the requirement to make a Hiroshima device 110 pounds [50 kg.] of U-235 enriched to 95 %. The Iranian close. Very close.

As to what exactly Plan B Israeli style we might not want to know.
