Last week, just two days after U.S. President Joe Biden announced his decision to withdraw the last U.S. troops from Afghanistan by Sept. 11, the humanitarian community commemorated the death of Marla Ruzicka, a humanitarian hero from the early years of the war there.

But in the interest of vigorous debate, let me suggest that their nostalgia for the 19th century is misplaced. The anachronistic mechanism they propose would not cure what […]
