You have to define “the Afghanistan tragedy” before you can answer the question.
IF the Taliban decide to facilitate the removal of Westerners from their country, the only “tragedy” is Afghans getting to live the way they want to.
Of course, an 1842-style retreat from Kabul is possible, in which case the meaning of “tragedy” would be undisputed.
If this triggers a regime crisis in the US, “US tragedy” is certainly possible. But I bet the fraction of the US population that would support regime change here is growing fast.
