A paradox of President Joe Bidens decision to end the war in Afghanistan is his vow to keep fighting the wider battle against terrorism even in the country he has just abandoned.

It has been a theme of Bidens administration since he announced the unconditional withdrawal in April. The president has talked of an over-the-horizon capability that will allow us to keep our eyes firmly fixed on any direct threats to the United States in the region. After the suicide blast at the Kabul airport last week that killed 13 American service members, Biden promised to hunt down the perpetrators. On Tuesday, Biden warned the perpetrators of that attack, ISIS-K: We are not done with you yet.
