Known Unknowns

Ann Althouse:

The number of Americans who have died in the Iraq war…

has now surpassed the number who died in the 9/11 attacks.

ADDED: A key question — with an unknowable answer — is: How many Americans would have died in post-9/11 attacks if we had not chosen the path of fighting back?

Leaving aside the curious “path of fighting back” construction (against whom were we “fighting back” in Iraq), we can probably estimate the “unknowable answer” here by projecting forward based on the total number of Americans killed in Iraq-sponsored terrorist attacks from 1991-2002: Zero. To be generous, a handful of American soldiers might have died trying to enforce the no-fly zones had there been no invasion.
