True but say they were simultaneously detonated on purpose. Assuming you could time that. THAT would be some impressive applied physics.
It would take all of the weapons in that one bunker to cripple / destroy all of Iran’s targets. I can’t remember how many there were but I remember at least two dozen targets. I counted at least 44 weapons there. Almost two per target.
In “The Day After”, you’ll notice the Russian strike is first an EMP burst at higher altitude, then the first real strike, followed by the second strike. I must confess I don’t know what the actual timing is but I suppose they were going for multiple warheads from the same missile platform. They got the X-Ray thing right though.
It’s even prophesied in Zechariah.
Zechariah 14:12 King James Version (KJV)
12 And this shall be the plague wherewith the Lord will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.
