The 9/11 era started with a bang (well four of them actually, one for each plane’s explosive impact) back in 2001. And to my mind the 9/11 era effectively ended yesterday - on the 18 December 2022 - with this spectacular fireworks extravaganza in Qatar: 

It was Qatar’s government that employed 9/11’s Engineer Khalid Sheikh Mohammed (KSM)
for the first three years of his terrorist spree, from 1993 to 1996. 

It was a member of the Qatari royal family that helped KSM avoid CIA capture in 1996. 

It was the Qatari security services who in 1998 kidnapped, renditioned and imprisoned their dissident
police chief who had warned CIA veteran Robert Baer that “KSM is going to hijack some planes" 

It was the Qatari government who employed the CIA and FBI agents who failed
to stop 9/11, with very lucrative contracts via the former Mayor of New York city

And it was the Qatari state that bribed FIFA  and European Union officials
so it could complete its sports washed transition to a state beyond reproach
- everyone who should be investigating Qatar is already on their payroll. 

9/11 was the most successful (for the war mongering military industrial complex) and spectacular terrorist attack ever, not because KSM and his associates were so clever, but because the general population of America and Europe were and remain so blinded by brainwashing, distractions and propaganda. 

Qatar, their backers and accomplices have got away with facilitating 9/11 because the West’s
general population is collectively still too stupid/sedated to realise what was done or by whom.
