Forces from Afghanistan's National Directorate of Security escort alleged Taliban and Islamic State fighters in Jalalabad on May 23.
He also warned Europeans to take back nationals captured fighting for the Islamic State, or he will release them back to their countries.
Asked by journalists if he is concerned about the reemergence of the Islamic State group in Iraq, Trump said forces under his lead had wiped out the extremists' caliphate.
"At a certain point Russia, Afghanistan, Iran, Iraq, Turkey, they are going to have to fight their battles too."
"We wiped out the caliphate 100 percent. I did it in record time. But at a certain point, all of these other countries, where ISIS is around ... are going to have to fight them. Because do we want to stay there another 19 years? I don't think so."
He singled out India and Pakistan as frontline countries that are doing little to fight jihadist groups.
"Look, India's right there, they are not fighting it, we're fighting it. Pakistan is next door. They're fighting it, very little.... it's not fair. The United States is seven thousand miles away," he told reporters.
Comment: Trump's right, but what he doesn't mention is that there was no good reason for the U.S. to travel 7,000 miles away to fight jihadists in the first place. It was the American war on terror that created ISIS and expanded the number of jihadists exponentially. But what's done is done, and now it will be up to those other countries to clean up the mess made by Trump's predecessors. Maybe they'll do a better job at it.
