What is wrong with some Americans? Why do they insist on going to places like North Korea and Iran, where governments are openly unfriendly to all Americans. Don't they get a memo when leaving the country, "Fellow citizen, go ahead, enjoy the world. Just stay out of NK and Iran. If you go there, we will not come and get you. We have enough problems to deal with already. Get it?"
