You are over thinking it. A tinfoil hat is not required.
The assault was an act of war pure and simple. It was merely another raid with the death of a very high value target as the outcome. It was well conceived and carried out.
It was a military operation and the source of the men who carried it out is unknown. There is a very good probability that some or all came from afar.
I don’t think so.
I suggest that the absence of 0bama and Biden from intelligence briefings makes for some kind of public ‘plausible deniability’ excuse that “we weren’t told.”
I am mean enough now to think that this was planned and happened exactly as it was executed...on both sides.
Dead men tell no tales. Bonus features: America is weakened, made to pay, and made to look vulnerable, all at the same time.
