FTFY
Pearl Harbor is very much on US soil.
The attack was planned by a group that wasn't the internationally recognized leadership of any country, and they hid in a war-torn country whose government was being violently contested. And the Taliban were also not recognized, at least not officially, as the leadership of Afghanistan.
So to call it an act of war is indeed a stretch.

Sure, there will always be people who think this not "real" war. But that's an irrelevant classification detail to the belligerents or the people caught up in the collateral damage.
9/11 was not an act of war. It was the work of a few deranged cultists who got lucky, nothing more and nothing less. Our response was equivalent to reacting to the Branch Davidians by bombing the Vatican.
Fast-forward 20 years to 9/11. Osama Bin Laden is funded by his family, and by other rich Saudis, which means the government of Saudi Arabia because all Saudi wealth is owned by the House of Saud.
But they're our allies, so instead, we attacked Iraq and Afghanistan, even though none of the 9/11 attackers were from either country. To get approval, we lied about Weapons of Mass Destruction, which we never found, because they didn't exist.
I'm not really following your war narrative, but I am finding a lot of cronyism and false flags.
My point was limited in scope to the 9/11 attack itself. I think terrorism on that scale can be classified as assymetric warfare.
Warfare predates nation states. Today, most of the world is parceled into nation states. But violent non-state actors never ceased to exist. And therefore we shouldn't limit our definition of warfare only to war between nation states.
