WOPR makes no sense

I have SO many questions.

Wasn't the whole idea that president could basically order the computer to launch missiles, so they wouldn't be 'at the mercy of the men with the little brass keys'?

Yet, we're shown exactly THAT, but with only ONE guy with a key, and it all happening in the command center main room.

What kind of sense does that make? One guy turns a key, lifts a plastic and has his thumb ready. No other guy with another key required, no massive, secretive bunker system with a fake house required, it all happens by one guy in the main command room. What?

Also, for a computer that plays an 'endless series' (surely the series MUST end at some point, even if it repeats the series, even if it comes up with 'new scenarios' constantly, there are only limited resources due to limited amount of countries and missiles, so by definition, it can't be 'endless', but it HAS to repeat itself at some point), it sure hasn't played ANY of the scenarios it plays in the end!

This could be excused if it was some 'general military computer' with other things as the main task, but THAT IS ALL IT DOES, so why hasn't it played ALL those scenarios already a thousand or more times? It doesn't take that long to play them, so what the heck?

Shouldn't it have learned 'you can't win the game' during about first 5 minutes of its operation?


Why can WOPR know David's number, when nothing and no one else in the same building/area can? Why wouldn't WOPR share this information, and why can't they look at the logs and access everything WOPR knows?

Who pays WOPR's phone bill when it calls David?

Why can't they simply check the LOG FILES to confirm/deny David's claims? If it shows WOPR actually did call him, that would clear David, right? Why won't they do that?

I have so many questions, but my computer is acting up, so I keep losing everything I write, so I can't continue this right now.
