This week Moscow experienced its biggest drone attack ever, and the images are unbelievable.

I know there are lots of videos saying Russia is collapsing or finished. This isn’t really one of those. I wanted to try and understand why Ukraine is doing this, and whether the aim is as psychological as it is physical.

It reminded me of my interview with Robert Brovdi a few months ago, so I thought it was worth bringing some of that context back.
