Yes, it is. But it may not be wise to. Just ask that kid from Ohio Otto Warmbier. Oh, that's right, you can't. That's because he's dead. North Korea arrested him for snagging a poster of Kim Jong Un that was plastered to a wall on the street for a souvenir, sentenced him to 15 years of hard labor, and then tortured him to death, or nearly to death, returning him to the United States a couple of years ago after just a couple of years in their prison system when he died days later without ever regaining consciousness.
