Actually, yes, I do. And France was not the only one...and we were not ignorant of the same rumblings, either.
However, warnings of attack, sedition, spying, etc... has been information shared among allies since the dawn of time.
Historically, it was hard for anyone (France would have been no different) to truly understand the scope of possibility...to even believe that such an extreme thing could be contemplated, let alone accomplished.
It's easy to say the US Govt was lazy, inattentive, whatever...but who truly could have believed such a thing? And how does one effectively respond to warnings of 'something significant' in the 'near future', anyway? It sounds good to say 'you were warned', but these warnings were entirely impractical and nearly impossible to respond to.
Yup, they sucker punched us, and thousands of us died so a pack of butchers and animals scratching sand out of their shorts can chest-thump and tell each other they 'won a victory' over the Great Satan.
Others have made that mistake...
(PS..To be fair, I assumed it was a typo, but don't think I won't defend my country and countrymen just as you would yours.)
