I think some of most interesting things around 9/11 are the extremely stupid side stories. Consider real estate developer Larry Silverstein who argued that the WTC attacks were two separate attacks, and therefore he was entitled to two payouts on his insurance claim.
It's mundane shit like this that really gives a unique glimpse into the depravity of capitalism. The uninteresting part of this is the casually anti-Semitic implication that the insurance policy was taken because a Jewish man knew what was going to happen. That's part is just stupid antisemitism and I do think it's worth making that point clear.
Is it really so unfathomable that some members of the US ruling class had advance knowledge of the attacks, when we know for a fact that the Saudi govt did? It's not like Larry's just some unlucky jew picked at random, he's the owner of the buildings! The meme's a bit puerile and I can't say for certain that the creator wasn't an antisemite, but the point holds.
