Here is a recent Scott Adams Dilbert cartoon, although Dilbert himself is not involved in this particular one:
I’ve always thought that one of the many things that won the Cold War for Civilisation and doomed Bolshevik Barbarism to defeat was stealth stuff. By its nature, stealth stuff is undetectable, and the better it is, the more impossibly undetectable it is. So, if you cannot detect it at all, it could still be there, and really really good at being stealthy. Hell, it could be anywhere. It could be right outside the Politburo’s front window.
Of course, it probably isn’t this clever. But, how would you be sure?
This was why, when the Americans had got these contraptions working reasonably well, they revealed their existence. They took lots of spooky photos of these spooky things, and made sure the whole world could see them. Where, at any particular moment, they were, for you to photo, they did not reveal.
How can you defeat an enemy like that?
Same with Star Wars. Shooting down all incoming nuclear missiles with all-powerful death rays. Bollocks, right? But, again, how could you be sure.
