HINT: It wasn’t the 1962 Cuban Missile Crisis – that was a distant second on the list
The 53rd anniversary of the United States’ closest-ever nuclear confrontation event will soon come and go with nary a mention of its significance – certainly not in the “Main Stream Media” (MSM) where it should appear, but probably very little in the “alternative” press either.
That is because it is still shrouded in secrecy, for the sake of protecting the presidential legacy of a man generally mis-designated as one of the ten “best” presidents of all time by people who self-identify as credentialed “historians,” who are purposely ignorant of the incident because knowledge of it is not “politically correct.” The ironies abound, given that this incident was merely another – and not even the worst – of his treasons.
The documented facts (at least by the BBC and Al Jazeera, since no American MSM source ever investigated it) are that at 8:45 a.m. EDT (2:45 p.m. off the coast of the Sinai Peninsula) on June 8, 1967 two A-4 bomber aircraft loaded with nuclear bombs were dispatched from the aircraft carrier USS America, bound for Cairo with orders to drop those bombs on that city.
