U.S. President Donald Trump hinted on Thursday he may visit Afghanistan, scene of one of America’s longest wars but a country he has yet to visit almost two years into his presidency, Reuters reported.

Asked by a reporter whether he would visit a war zone, Trump said: “At the appropriate time, we’ll be doing some very interesting things.”

He was then asked whether he knew the timing: “I do, but can’t tell you. You’re the last people I can tell,” he told reporters. Presidential trips to war zones are normally cloaked in secrecy for security reasons, revealed only when the commander in chiefs have landed, and sometimes only after they have safely left the region.

Responding to criticism that phoning the troops on Thanksgiving was not enough, Trump defended his actions, arguing that he had hiked spending on the military and veterans.
