There are a lot of organizations in the world, corporate, criminal, and otherwise, that can muster say $25 million (which, I admit is a number I just pulled out of my ass) to accomplish a monumental task. I'm just not sure that I'm ready to believe that the money amounts we're talking here are restricted only to the wealthiest of nation states. Is the claim that you would need literally billions of dollars to get the smart people and equipment?
