I have researched this stuff for 20 years.
Basically every US war started with a false flag e.g.
WW1 Lusitania
Vietnam Gulf of Tonkin
Suez war was a failed false flag attempt USS Liberty after the US told Israel to bomb their own ship but Israel fucked it up and didn't kill everyone so the witnesses let people know it wasn't an Egyptian hit
Both Pearl Harbour and 911 were plots that the ABCs knew about but let happen in order to use them as a pretext to go to war. In other words 911 did involve Muslim terrorists but they the Feds let it happen and/or helped the Jihadis along a little bit.
