Everyone criticizing the war in the middle east always seems to casually forget that terrorists from this region hijacked airplanes and destroyed the two tallest buildings in the US with them, killing thousands.
I'm not trying to argue that Saddam Hussein was a nice man... But that's a stretch to still attempt to justify the US invasion of Iraq with 9/11. That's like saying the US should attack Germany because some the 9/11 hijackers lived here and studied here. And France, because "it's in the region". Or bombing Canada because Mexican narco criminals repeatedly murdered US citizens and Canada happens to be in the region (and supports narco terrorism by buying some of the drugs).
Most of the 9/11 attackers were Saudi nationals, none were Iraqi. The "mastermind", according to US intelligence, was bin Laden, a Saudi national (who was technically stateless after his citizenship was stripped by the Saudis long before 9/11), who resided in Afghanistan and Pakistan (and Sudan and Saudi Arabia before that). The US Senate investigation found that Saddam Hussein and the Iraqi nation had no role in 9/11.
Did Ukraine do anything like that to Russia?
