I agree, but only because I’ve seen the video. Stills of missile plumes/contrails can look very like each other - they’re simply not conclusive.
The video shows a rocket. Given that the firing position is right in the middle of a naval missile testing base, we can hazard a guess as to the nature of the rocket: it was Navy.
Maybe an unscheduled launch, maybe a complete accident - for all we know this was a cook-off of a solid fuel booster.
you just need to force your brain to see the bottom left as being much further away than the top right, and it will become clear to you.
