Because Iranians wouldn’t remove someone else’s mine.
Someone else uniformed as Iranians might remove a fake mine.

“Because Iranians wouldn’t remove someone else’s mine.”
You’re assuming it is the Iranians in the video.
Could be Saudis, or some other Gulf State, removing the UXO evidence of what they had done.
Saudis see higher oil prices and maybe the U.S. attacks Iran.
It’s a better motive than anything I can come up with for Iran. They pick a fight they just get their Navy destroyed like they did 30 years ago.
