Wouldn't a a slow-moving C-130 make an easy target itself?
The destruction of ground surface targets is straight forward: Initial strikes blind the radar and destroy air defenses, the enemy air power is annihilated and then the ground surface targets can be destroyed at leisure by either pin-point guided munitions or by B-52 carpet bombings. A MOAB would look more impressive but is not really necessary.
The real dilemma in this air campaign will be the feasibility of destroying hardened, deep below-ground facilities with conventional bunker busters.
I have NO military expertise.
However, I read novels.
here's the plan........
The military launches a secret attack on an ally in the ME.
Blame it on iran.
Retaliate by destrying everything that moves in iran with nukes.
Problem solved.
Yeah I know, it would never work.
B-2 don't carry air-launched cruise missiles. MOABs would not be used for any attack on Iranian targets. The delivery vehicle is just far too slow and vulnerable. Think of the use of stealth in the initial strikes backed up by ALCMs. That would just be the start of the campaign to defang Iran's nuclear ambitions.
It would require an intense military campaign to take out military airfields and air defense systems. Their naval forces would have to be taken out to stem any thoughts of closing the straits of Hormuz. Not an easy task, but the US has the means and methods to do it alone.
The biggest problem is that if the Israelis strike at Bushehr for example then the Iranians will simply not believe that the US wasn't involved. Vice versa for a US strike. Iran will retaliate with Shahabs etc.
More that likely the US will have no other option but to follow up any Israeli strike with full military action of their own. An Israeli strike would simply stir up a hornets nest in the region. Iran's regime would try to retaliate against US forces in the region so it would be better if Iran was defanged with an intense military campaign.
