It's over. The long national nightmare of navel-gazing, self-pity, self-indulgence, and excuse-making has at last come to an end.This is your official notice: effectively immediately, the phrase "post-9/11 world" is obsolete. It has been permanently retired.
It had a good run. A full decade. I have even given you an extra day or so of leeway. But "post-9/11" must now go. For to keep it around, whether out of laziness, convenience, or just force of habit, would be to cheapen and debase it (further). We don't refer to a "post-Berlin Wall" world, do we? Or "post-JFK"? History is too far advanced for us to still be "post-Civil War" or even "post-World War Two".
Should you find someone still using the phrase "post-9/11 world", please remind them: We are now officially in a "post-post-9/11 world". The use of the phrase "post-9/11" is no longer acceptable.
