Harris identifies the crash of Flight 175 into the South Tower as the instant September 11 became an unmistakable historical rupture.

The brief

On the 25th anniversary of September 11, Sam Harris revisits the moment when the second plane made the attack’s scale and intent unmistakable, turning a bewildering morning into a historical dividing line.

The reflection returns to the intellectual climate surrounding The End of Faith and argues that Western institutions failed to take jihadist ideology seriously enough before the attacks and in their aftermath.

Harris follows the consequences through the war on terror, the abandonment of Afghan allies, and the unresolved costs of interventions in Afghanistan and Iraq.

He also considers perceived continuities between September 11 and October 7, alongside disputes over Islamo-leftism and the political misuse of “Islamophobia.”

The standout idea is that Flight 175 supplied not merely confirmation, but a permanent before-and-after boundary for anyone who witnessed it unfold.
