>warn people about planes
>hijacking is stopped successfully
>towers blow up anyway

So let me see if I understand this
>A group of men were reported to have been watching the twin towers burning and falling and they were celebrating and dancing
>Group is later arrested, say they are part of a moving company. Owner of moving company is found to have fled to Israel
>After 70 days group is deported to Israel and revealed to be Mossad agents who were sent to "document" 9/11....before it happened
>Israel knew the exact time, place, when where how and why of the 9/11 attacks...but instead of warning "their greatest ally" they chose to send some agents to document it and celebrate
>USA decides to invade Afghanistan for...reasons.
So despite this being common knowledge, we still bend over backwards to Israel despite them knowing in advance and laughing at our greatest tragedy?

The only question I have is, why?
