Each of U.S. President Joe Biden’s three predecessors—George W. Bush, Barack Obama, and Donald Trump—had to decide what to do about the United States’ unsuccessful nation-building effort in Afghanistan. Each chose to kick the can down the road and prolong an unwinnable war. They did so either because they believed a bit more effort would turn the tide or because they were unwilling to challenge a foreign-policy establishment that did not know how to win the war yet insisted it be allowed to keep trying.
Biden has rejected this outdated advice and announced that U.S. combat forces will leave by Sept. 11. He recognized that pleas for a “conditions-based” withdrawal made little sense because the specified conditions were beyond the country’s grasp and this policy would have kept U.S. forces there forever. Biden’s decision was both courageous and correct, but he will now face endless second-guessing from hawkish critics convinced the war could somehow be won and by Republicans looking to exploit the issue. He should give these naysayers the attention they deserve—that is to say, none—and so should you.
