意味（1）

The date of the attack on the Twin Towers and the Pentagon in the USA, September 11th, 2001.

意味（2）

(metonymically) The attack itself.

What is unbearable, in fact, is the feeling, 13 years after 9/11, that America has been chasing its tail; that, in some whack-a-mole horror show, the quashing of a jihadi enclave here only spurs the sprouting of another there; that the ideology of Al Qaeda is still reverberating through a blocked Arab world whose Sunni-Shia balance (insofar as that went) was upended by the American invasion of Iraq.
