With that kind of expectations, what's to keep the president and military from having to declassify every military objective just for the sake of armchair generals? Might as well keep nothing classified. If we were to have a strategy to invade NKorea, then by your standards we should declassify our moves and strategy to the whole world. That sounds assinine.
It was a matter of faith in government to expect FDR to contain hitler and defeat the japaneese. He didn't have to declassify his military strategies. But i'm thankful lefties like you didn't exist back then, since that would of secured hitler every chance to have us speaking german.
