An act of war by whom? Which nation? Osama Bin Laden was trained in the United States by Reagan's authority when he funded/supported the Mujahadeen in a proxy war against Russia.

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.
