I used to work for several of the US intel agencies. I can say with great confidence that we never have acted gainfully on preventing a major event using intel and we never will. The catalyst for acting boldly to prevent or defend a major event is much mor political than informational. No intel will ever play a big role in deciding whether a country lives or dies. But we most certainly WILL abuse individual civil rig…
> The catalyst for acting boldly to prevent or defend a major event is much mor political than informational. Could you explain what you mean by this? On a tangential note, have you considered talking/explaining this with politicians/academics studying this field? Or is it more of something that's already known to those familiar with the field?
So even as damning and revealing as the Zimmerman telegram was, ultimately it was Germany's bold resumption of the torpedoing of US oceangoing traffic that catalyzed US public opinion into ending 3 years of American neutrality and joining the fight in WWI. Thus even when intel is most damning, the role of intel will always be subservient to publicly motivating events like lost lives, as in the much ballyhooed sinking of the Lusitania 2 years before (1915).
