No, the US normally does not wait for the public to know the truth, but the US does wait until they’ve won public sentiment, even if that sentiment is based on shit, and most times it is.  Truth or lie, if you don’t have public support, the public could revolt.    In addition, this ‘truth’ is not comparable to any other truth in any of our lifetimes.  This is the grand daddy of them all.  The mother of all truths.  I want those arrests too, and I want them fucking bad, but I would also like to avoid WW3 if at all possible.
