And Pakistan has also historically had nukes - they were first obtained in 1998. This [1] page offers a variety of data on terrorism. I recommend selecting the "terrorist attacks by region" graph as it illustrates it most clearly. At the time of 9/11, global terrorism was in its death throes. 9/11 was a Hail Mary by Bin Laden and it's been a resounding success. Global terrorism has exponentially skyrocketed since the war on terror.
And on top of this terror groups are now growing powerful enough to fully control their own countries. The Taliban now has rock solid control of Afghanistan (before the war on terror they had majority control, but were struggling against a powerful insurgency), Abu Mohammad al-Julani controls Syria and US propaganda is framing him as a moderate or reformer, but he's not. He had a $10 million bounty on his head as one of the most dangerous terrorists in the world, even as we started running propaganda for him, exactly as we did for [de facto] Al Qaeda(from which he came) before they came back to bite us later, exactly as he will. Then there's the Houthis who went from a political movement to an insurgency to now having near complete control of Yemen in spite of ongoing conflicts with Saudi Arabia and the US.
