No. I think it would be more useful if we learned from past mistakes.
But we as a Nation don't. We don't even learn from the founding fathers.
Kind of like Zbig's statement to Carter that we lured the Ruskies into their VietNam.
Sad, very sad but very true.
But, I have seen many articles recently about how we funded Afghanis' resistance to the Soviets and the impression I get from all of these is that the reader is supposed to conclude that since we supported that which we now fight, we should desist in shame.
