Supposedly tactical nukes were used by Saudi Arabia back in 2015, it's not the Davy Crocket nuclear bazookas of the 50's, we're talking low radiation, high yield explosives that leaves little trace radiation compared to the ballistic nukes. Yet there's not interference on the camera, regardless if it's film or digital.

My view is inconclusive, if it's CGI they're using a lot of high quality effects for light scattering, not something I'd expect for a private hoax and the motion tracking for overlays is basically PERFECT.

I'm absolutely sure people could use tactical nukes and keep it "unverifiable".
