They ain't got the logistics.

They could do it for a small/mid-ish sized city; lots of logistics.
Also, it wouldn't take a large team to instigate the real false-flag incident... the rest is "counter-terrorism" response.

They can't do it for the country. I've run the numbers.

The might of the western world can't control Afghanistan. Forget flyover America, where guys like me have lathes and milling machines.
