After 13 years, the U.S. officially ended its combat role in Afghanistan on Monday. In two weeks, another troop withdrawal will leave less than 11,000 U.S. soldiers in the country.

This comes as the Taliban has increased its attacks across Afghanistan, leaving dozens dead, including two U.S. soldiers who were killed in a suicide bombing on Friday.

Gen. Anthony Zinni (ret.) said on "Sunday Morning Futures" today it's important that the the U.S. continues training and equipping Afghan security forces, but most importantly, Afghanistan President Ashraf Ghani needs to step up and give the people something to fight for.

Zinni said that around U.S. 11,000 troops should be enough, as long as we maintain several capabilities, including special operations that can hit high-value targets, in addition to the continued supply of advisors, trainers and equipment to help the Afghan army.

Zinni reiterated that in Afghanistan - and Iraq, for that matter - it's more about the new leadership in the government than direct U.S. involvement.

"I don't think us staying there forever and continuing to fight the Taliban or ISIS and other elements is going to get it. We have got to get these countries to stand up on their own. It's time to take off the training wheels."
