I am ready to call the collapse of the R4 fuel pool at Fukushima.

It's down.  They are cutting and dragging huge chunks of steel and concrete around that building.  They would not do that if the pool hadn't already collapsed.

This is the video of the last hour at R4.

As Groucho Marks famously quipped:  ” If you think the country's messed up now, just wait 'till I get through with it”.
