Stirling, but look at JFK
again, all those 'facts' that made things look not right, which gained currency somehow over the years, turns out they are wrong.
These happened in the 60's mostly, much less TV
, fewer and lower selling tabloids, no internet.
So imagine a much more complex event like Sept 11th, in todays media saturated world.
I'm no builder, or structual expert, but I've heard plenty of reasonable sounding explanations to all the buildings that fell, by those qualified to do so.
The Mossad agents in the US, looking at the Arab community in NY/New Jersey by any chance? Israel has spied on the US for technology-why not potential funding souces for Arab terrorism, look at the 'Irish Americans' and the IRA, jumping for joy, has been debunked.
Silverman just looks like a grubby, tight arsed type-witness the troubles over developing the site. An important thing for NY and the US, but not a jot of that concern from Silverman.
But you are right, at the risk of being flamed, Sept 11th was partial 'blowback'.
Unintentional of course, often from events years in the past, often seeminly unrelated.
But the history of funding hard core Islamists to fight the USSR
in Afghanistan, the decades of 'looking the other way' as Saudi Arabia funded very hardcore breeds of Islamism, the continued presence of US forces in Saudi post 1991, the continuing and accelerating relative failure of Arab nations with (Western supported) despots, in wealth, education etc.
This and much more, all came together in the 1990's, with a strand of militant Islam bent on sticking a finger in the eye of a Superpower-hadn't they, in their own view, driven the USSR
out of one Muslim nation already?
Successive US governments, have usually unwittingly, helped the situation above to evolve.
As you say-it not a big conspiracy-but, as usual, a succession of cock ups by fallible people.
With the potential to cause some very red faces.
For me, most conspiracy theorists are far from 'open minded', quite the opposite, usually they are obsessed.
Even more usually, those who start them have an axe to grind, using doubts about unusual events as a way of getting at the target of their dislike.
Always remember, the biggest proponents of a conspiracy theory were the Nazis.
Using age old anti semitism still latent, the humilation of WW1 and the aftermath, the terrible economic conditions in the late 20's/early 30's, to advance a worldview based on some pretty nonsensical fears and outright lies for their 'Jewish Conspiracy'.
