This latest attack is another example of the failed US withdrawal from Afghanistan. The Islamic State group was virtually eradicated before the US's botched retreat last year, and now its Khorasan affiliate is back in the game attacking diplomatic buildings and killing civilians. This attack on Chinese nationals may prompt Beijing to take on a more constructive role to clean up the mess left behind by Washington.
Beyond its empty promises to build a more inclusive government, the Taliban has failed to back up its pledge to prevent Islamic State group terror attacks on its soil. Even with billions of dollars worth of weapons and equipment, the new Afghan Taliban government has yet to set up a functional army, which is key to combatting this threat.
