That is as it's always been.
Tet was a perfect example. Unit commanders who viewed provided intel with suspicion were surprised and their units paid the price.
Better Unit commanders who listened were ready and kicked Charlies butt.
I don't think you quite understand what I am saying. What I mean is now, whenever we go on the tube or in front of the world and say "our intel indicates Iran has ten nukes and is ready to sell them to terrorists," those in the media and others will say, "wait, that's what you said about Iraq's WMDs and they were not there." I am not saying individuals leaders but the nation as a whole will be led down a path of non-believing. Get my drift?
