> No increase in radiation levels have been detected, the UN's nuclear watchdog says

If true they failed to destroy the material (just like last time when the US brought chaos over the world by creating a war out of "they have bombs" lies)

If not true, did they actually try to make the world a more poisonous place?

The material cannot be destroyed. However, uranium hexafluoride is very heavy and won't go far. Also, it reverts into a solid at ≤ 56 °C. Finally, it has a very long half life, meaning it is not super radioactive.

Not true. Caverns can collapse without leaking enough into atmosphere to trigger detection. The simple answer is we don’t really know; we may not be able to know.
