Sorry, but it is impossible when it comes to subjective matter.

guest, that's a cop out and you should know it. You can not compare apples to organges to "prove" your point. First hand accounts by individuals will give one perspective... but it's official documents that provide most source material and then correspondance and diaries from those officials that help back up conclusions. Last time I checked, Joe Blow on the street did not have the authority to declare war.

Will we ever know everything? Of course not, but we can and do have the ability to figure out more than you seem to give credit to.
