Much of the coverage of America’s exit from Afghanistan has focused on the chaos at the Kabul airport, the vital challenge of getting Americans and Afghans out of the country, and the lives saved. Of longer-term importance is how the Taliban takeover of Afghanistan will affect Americans here in the United States. U.S. transportation networks, with their dependence on technology, are particularly vulnerable.

Afghanistan now gives terrorists a base to launch coordinated, sophisticated attacks against the United States, as was the case on September 11, 2001. Those attacks and many others targeted transportation systems.
