Well, you and I clearly differ.
For example, you classify all intel as "guesses" apparently. Intel is a tough business. You can show two highly qualified photo interpreters the same photo and they often will deduce diifferent things from it. To Nash, apparently, these are "guesses". Maybe they are.
That doesn't mean that National Command Authority can disregard the two interpretations; it means somone has to make a decision and formulate policy from one of those reports. Sometimes a decision to go to war result from this chain of events.
You ever had to make a decision where people's lives were in the balance? Make the right decision, everyone lives; make the wrong one and everyone dies? Somebody has to make decisions like that. You use the best available information you can get and then you have to make the call. Second-guessers always look brilliant after the fact but it's rarely so cut and dried for the guy having to make the call.
You can say it's wrong to support a war based on what the government tells you. You can feel all good about being so right. You can even brag on how well you guessed if you like. I chose to believe my government and I don't feel that was wrong. Sorry.
Now, if you have an incontrovertible information that the guesses were based on "complete lies" please link it. And pass it on to the US Congress as well.
Or are you just going by what you read in the media?
