One of the most searing images in America’s military history is that of untold numbers of terrified South Vietnamese civilians trying to board the last helicopter on the roof of our embassy in Saigon in April 1975. It captured both our nation’s humiliating political defeat in the war there at the hands of impoverished, but relentless, communist enemies and presaged the horrific toll they would exact on those we abandoned.

The prospect of an imminent reprise of that disaster is on the minds of Afghan leaders with whom President Biden is meeting today. After all, we’re poised to leave them to their fate at the hands of no-less-ruthless Taliban jihadists emboldened by Mr. Biden’s decision unilaterally to walk away from the so-called “endless war” in Afghanistan.

Treating allies this way ensures we will have fewer friends and more enemies.
