People are saying this seems like it's getting closer to happening. And a huge percentage of people are against it.
I heard Erik Prince, who knows this stuff, say that a bunker buster isn't that hard to make. You basically take a huge shell, which is easy enough to find, and stuff it full of enough explosives to do the job. Israel could have made these years ago if they'd wanted to. And they already pretty much own the airspace, so this idea that you have to fly at 30k feet for this mission is bogus.
Hopefully they're just putting things in place so it doesn't take as long to execute if called upon. Or even better, this is a bluff to get the Iranians to surrender... which probably won't happen.
Hope I'm wrong, but this has bad news all over it.
