I agree the dancing Israelis are pretty much a smoking gun that Israel was either directly involved or knew the details of the attack beforehand. There just isn't any real innocent explanation for their actions, and we know for a fact they were mossad agents. That they were released and never questioned again and this was immediately buried in the media and memory holed is also further proof of how much power the Israelis and the zionist diaspora have over the US government and media.

Whether the Israelis directly had a role in the attack is harder to say. I don't believe the nonsense about drones or cruise missiles, and I doubt explosive charges were used to bring down the twin towers. There were clearly planes hijacked and flown into buildings and it has been sufficiently explained how the towers collapsed(WTC 7 is still suspicious though and it's possible that was greed and brazen chutzpah on the part of Larry Silverstein who wanted to collect on the massive amount of insurance money after being forewarned in some way of an impending attack).

The question to me is whether the hijackers and Al Queda were unwitting stoodges funded, protected and possibly even organized by Israelis and/or neocons, or whether they were simply Muslim extremists doing Muslim extremist things and the Israelis/neocons tried to prevent them from being found out beforehand. I think the latter is more likely, but given the depths of neocon depravity and false flagging we've seen with Ukraine I no longer put anything past them.
