President Obama is entering his last year in office. All week, we’ve been discussing his unfinished business. Today: Afghanistan. With U.S. forces being drawn down, the Taliban has been resurgent. The group holds more territory now than it has at any time since it was ousted from power in 2001. The Islamic State group is also gaining a foothold. Yesterday, seven people were killed in an Islamic State attack in the city of Jalalabad. The U.S. has concluded that Afghan forces are not ready to hold the country against insurgents, so American troops will remain. President Obama announced last October that we would maintain between 5,000 and 10,000 troops in Afghanistan through the end of his time in office. We examine the situation.
